Back Clinic Nerve Injury Team. Nerves are fragile and can be damaged by pressure, stretching, or cutting. Injury to a nerve can stop signals to and from the brain, causing muscles not to work properly and losing feeling in the injured area. The nervous system manages a great majority of the body’s functions, from regulating an individual’s breathing to controlling their muscles as well as sensing heat and cold. But, when trauma from an injury or an underlying condition causes nerve injury, an individual’s quality of life may be greatly affected. Dr. Alex Jimenez explains various concepts through his collection of archives revolving around the types of injuries and condition which can cause nerve complications as well as discuss the different form of treatments and solutions to ease nerve pain and restore the individual’s quality of life.

For individuals dealing with chronic pain conditions can having a better understanding of pain management specialists help in developing effective multidisciplinary treatment plans?
Pain Management Specialists
Pain management is a growing medical specialty that takes a multi-disciplinary approach to treating all types of pain. It is a branch of medicine that applies scientifically proven techniques and methods to relieve, reduce, and manage pain symptoms and sensations. Pain management specialists evaluate, rehabilitate, and treat a spectrum of conditions, including neuropathic pain, sciatica, postoperative pain, chronic pain conditions, and more. Many primary healthcare providers refer their patients to pain management specialists if pain symptoms are ongoing or significant in their manifestation.
Specialists
Healthcare providers specializing in pain management recognize the complex nature of pain and approach the problem from all directions. Treatment at a pain clinic is patient-centric but depends on the clinic’s available resources. Currently, there are no set standards for the types of disciplines needed, another reason treatment options vary from clinic to clinic. Experts say that a facility should offer patients:
A coordinating practitioner specializing in pain management and consulting specialists on the patient’s behalf.
Other specialties represented in pain management are anesthesiology, neurosurgery, and internal medicine. A coordinating healthcare provider may refer an individual for services from:
A healthcare provider should have completed additional training and credentialing in pain medicine and be an MD with board certification in at least one of the following (American Board of Medical Specialties. 2023)
Anesthesiology
Physical rehabilitation
Psychiatry
Neurology
A pain management physician should also have their practice limited to the specialty they hold the certification.
Management Goals
The field of pain management treats all types of pain as a disease. Chronic, such as headaches; acute, from surgery, and more. This allows for applying science and the latest medical advances to pain relief. There are now many modalities, including:
Medication
Interventional pain management techniques – nerve blocks, spinal cord stimulators, and similar treatments.
Physical therapy
Alternative medicine
The objective is to minimize and make symptoms manageable.
Individuals determined that surgery does not benefit their condition.
A better understanding of pain syndromes by communities and insurance companies and increased pain studies will help increase insurance coverage for treatments and technology to improve interventional outcomes.

Individuals feeling tingling or pins and needles sensations that overtake the arms or legs could be experiencing paresthesia, which occurs when a nerve has been compressed or damaged. Can knowing the symptoms and causes help in diagnosis and treatment?
Paresthesia Body Sensations
The numbness or tingling feeling when an arm, leg, or foot has fallen asleep is not so much about blood circulation but nerve function.
Paresthesia is an abnormal sensation felt in the body due to the compression or irritation of nerves.
It can be a mechanical cause like a compressed/pinched nerve.
Or it may be due to a medical condition, injury, or illness.
The symptoms typically last for 30 minutes or less.
Shaking the affected limb often relieves the sensations.
Paresthesia usually affects only one arm or leg at a time.
However, both arms and legs can be affected, depending on the cause.
Consult a healthcare provider if the symptoms last for more than 30 minutes. Treatment may be required if paresthesia body sensations are brought on by a serious underlying cause.
Causes
Sitting with incorrect and unhealthy postures can compress a nerve and generate symptoms. However, some causes are more concerning and can include:
If the symptoms don’t go away after 30 minutes or keep returning for unknown reasons, call a healthcare provider to find out what is causing the abnormal sensations. A worsening case should be monitored by a healthcare provider.
Peripheral neuropathy caused by diabetes usually begins with a feeling of paresthesia in the foot/feet and can worsen and lead to other complications.
A healthcare provider will work with the individual to understand the symptoms and perform the appropriate diagnostic tests to determine the cause. A healthcare provider will choose the tests based on a physical examination. Common diagnostic procedures include: (Merck Manual Professional Version. 2022)
Magnetic resonance imaging – MRI of the spine, brain, or extremities.
X-ray to rule out bone abnormalities, like a fracture.
Blood tests.
Electromyography – EMG studies.
Nerve conduction velocity – NCV test.
If paresthesia is accompanied by back or neck pain, a healthcare provider may suspect a compressed/pinched spinal nerve.
If the individual has a history of diabetes that is poorly controlled, they may suspect peripheral neuropathy.
Treatment
Treatment for paresthesia depends on the diagnosis. A healthcare provider can help determine the best course of action for the specific condition.
Nervous System
If symptoms are triggered by a central nervous condition like MS, individuals will work closely with their healthcare provider to get the appropriate treatment.
If paresthesia is caused by compression of a spinal nerve, like sciatica, individuals may be referred to a chiropractor and physical therapy team to release the nerve and pressure. (Julie M. Fritz, et al., 2021)
A physical therapist may prescribe spinal exercises to relieve compression of the nerve and restore normal sensations and motion.
Strengthening exercises to restore flexibility and mobility may be prescribed if weakness presents along with paresthesia body sensations.
Herniated Disc
If a herniated disc is causing the abnormal sensations, and there has been no improvement with conservative measures, a healthcare provider may suggest surgery to relieve pressure on the nerve/s. (American Association of Neurological Surgeons. 2023)
In surgical procedures like a laminectomy or discectomy, the objective is to restore nerve function.
Post-surgery, individuals may be recommended to a physical therapist to help regain mobility.

Individuals diagnosed with peripheral neuropathy, or with small fiber neuropathy, can understanding symptoms and causes help with potential treatments?
Small Fiber Neuropathy
Small fiber neuropathy is a specific classification of neuropathy, as there are different types, which are nerve injury, damage, disease, and/or dysfunction. Symptoms can result in pain, loss of sensation, and digestive and urinary symptoms. Most cases of neuropathy like peripheral neuropathy involve small and large fibers. Common causes include long-term diabetes, nutritional deficiencies, alcohol consumption, and chemotherapy.
Small fiber neuropathy is diagnosed after diagnostic testing showing it is clear that the small nerve fibers are involved.
The small nerve fibers detect sensation, temperature, and pain and help regulate involuntary functions.
Isolated small-fiber neuropathy is rare, but research is ongoing on the type of nerve damage and potential treatments. (Stephen A. Johnson, et al., 2021)
Small fiber neuropathy is not specifically dangerous but is a sign/symptom of an underlying cause/condition that is damaging the body’s nerves.
Pain – symptoms can range from mild or moderate discomfort to severe distress and can happen at any time.
Loss of sensation.
Because the small nerve fibers help with digestion, blood pressure, and bladder control – symptoms of autonomic dysfunction can vary and can include:
Constipation, diarrhea, incontinence, urinary retention – the inability to completely drain the bladder.
If there is progressing nerve damage, the intensity of the pain can decrease, but the loss of normal sensation and autonomic symptoms can worsen. (Josef Finsterer, Fulvio A. Scorza. 2022)
Hypersensitivity to touch and pain sensations can cause pain without a trigger.
The loss of sensation can make individuals unable to accurately detect sensations of touch, temperature, and pain in affected areas, which can lead to various types of injuries.
Although more research is needed, certain disorders that were not considered neuropathies may have small fiber neuropathy components involved.
A study suggested that neurogenic rosacea, a skin condition, could have some elements of small fiber neuropathy. (Min Li, et al., 2023)
These small nerve fibers are distributed throughout the body including the tops of the fingers and toes, trunk, and internal organs.
These fibers are usually located in the superficial areas of the body, such as close to the skin’s surface. (Mohammad A. Khoshnoodi, et al., 2016)
The small nerve fibers that get damaged are involved in transmitting pain and temperature sensations.
Most nerves have a special type of insulation called myelin that protects them and increases the speed of nerve impulses.
Small nerve fibers may have a thin sheath, making them more susceptible to injury and damage at earlier stages of conditions and diseases. (Heidrun H. Krämer, et al., 2023)
Individuals At Risk
Most types of peripheral neuropathy cause damage to the small and large peripheral nerve fibers. Because of this, most neuropathies are a mix of small-fiber and large-fiber neuropathy. Common risk factors for mixed fiber neuropathy include: (Stephen A. Johnson, et al., 2021)
Diabetes
Nutritional deficiencies
Overconsumption of alcohol
Autoimmune disorders
Medication toxicity
Isolated small-fiber neuropathy is rare, but there are conditions that are known to contribute to the cause and include: (Stephen A. Johnson, et al., 2021)
Sjogren Syndrome
This autoimmune disorder causes dry eyes and mouth, dental problems, and joint pain.
It can also cause nerve damage throughout the body.
Fabry Disease
This condition causes a buildup of certain fats/lipids in the body that can lead to neurological effects.
Amyloidosis
This is a rare disorder that causes a buildup of proteins in the body.
The proteins can damage tissues like the heart or nerves.
Lewy Body Disease
This is a neurological disorder that causes dementia and impaired movement and can lead to nerve damage.
Lupus
This is an autoimmune disease that affects joints, skin, and sometimes nerve tissue.
Viral Infection
These infections typically cause a cold or gastrointestinal/GI upsetness.
Less often they can cause other effects like small fiber neuropathy.
These conditions have been seen to cause isolated small-fiber neuropathy or begin as small-fiber neuropathy before progressing to the large nerve fibers. They can also begin as a mixed neuropathy, with small and large fibers.
Progression
Often the damage progresses at a relatively moderate rate, leading to added symptoms within months or years. The fiber nerves that are affected by the underlying condition usually progressively deteriorate, regardless of where they are located. (Mohammad A. Khoshnoodi, et al., 2016) Medications can help alleviate damage to the peripheral nerves. For individuals that are diagnosed in the early stage, it is possible to stop the progression, and potentially prevent involvement of the large fibers.
Treatments
Treatment toward preventing the progression requires controlling the underlying medical condition with treatment options depending on the cause. Treatments that can help prevent the progression include:
Blood sugar control for individuals with diabetes.
Immune suppression for control of autoimmune diseases.
Plasmapheresis – blood is taken and the plasma is treated and returned or exchanged for the treatment of autoimmune diseases.
Symptom Treatment
Individuals can get treatment for the symptoms that will not reverse or cure the condition but can help with temporary relief. Symptomatic treatment can include: (Josef Finsterer, Fulvio A. Scorza. 2022)
Pain management can include medications and/or topical analgesics.
Physical therapy – stretching, massage, decompression, and adjustments to keep the body relaxed and flexible.
Rehabilitation to help improve coordination, which can be impaired by loss of sensation.
Medications to relieve GI symptoms.
Wearing specialized clothes such as neuropathy socks to help with foot pain symptoms.
Treatment and medical management of neuropathies usually involve a neurologist. A neurologist may prescribe medication to help alleviate pain symptoms and provide medical interventions like immunotherapy if there is concern that an autoimmune process could be the cause. Additionally, treatment could include the care of a physical medicine and rehabilitation physician or a physical therapy team to provide stretches and exercises to help strengthen the body and maintain mobility and flexibility.

How does spinal decompression help reduce somatosensory pain associated with individuals dealing with back and leg pain?
Introduction
As we all know, the human body is a complex system that works together to perform various actions without feeling pain or discomfort. With muscles, organs, tissues, ligaments, bones, and nerve roots, each component has its job and interacts with other body parts. For instance, the spine collaborates with the central nervous system to instruct the muscles and organs to function correctly. Meanwhile, the nerve roots and muscles work together to provide mobility, stability, and flexibility to the upper and lower body extremities. However, as time passes, the body ages naturally, and this can lead to unwanted issues. Normal and traumatic factors can interfere with the neuron signals from the brain and cause somatosensory pain in the upper and lower extremities. This pain-like sensation can affect each body section, making the individual miserable. Luckily, there are ways to reduce somatosensory pain and provide relief to the body. Today’s article explores how somatosensory pain can impact the lower extremities, particularly the legs and back, and how non-surgical treatments like spinal decompression can alleviate somatosensory pain in the lower extremities. At the same time, we work hand-in-hand with certified medical providers who use our patient’s information to treat and mitigate somatosensory pain affecting the legs and back. We also inform them that non-surgical treatments like spinal decompression can help alleviate residual pain-like symptoms from the lower extremities. We encourage our patients to ask essential and important questions while seeking education from our associated medical providers about their pain. Dr. Alex Jimenez, D.C., incorporates this information as an educational service. Disclaimer
How Does Somatosensory Pain Affect The Legs & Back?
Are you experiencing numbness or tingling in your legs or back that disappears after a few minutes? Do you feel questionable pain in your lumbar spine after work? Or do you feel a warm sensation in the back of your legs that turns into sharp shooting pain? These issues may be related to the somatosensory system within the central nervous system, which provides voluntary reflexes to muscle groups. When normal movements or traumatic forces cause problems to the somatosensory system over time, it can lead to pain that affects the body’s extremities. (Finnerup, Kuner, & Jensen, 2021) This pain may be accompanied by burning, pricking, or squeezing sensations that affect the lumbar region. Many factors can be associated with somatosensory pain, which is part of the central nervous system and works with the spinal cord. When the spinal cord becomes compressed or aggravated due to injury or normal factors, it can lead to low back and leg pain. For example, a herniated disc in the lumbosacral area can cause nerve roots to send pain signals to the brain and cause abnormalities in the back and legs. (Aminoff & Goodin, 1988)
When people are dealing with back and leg pain from somatosensory pain, it can cause them to be miserable by reducing their quality of life and leading to a life of disability. (Rosenberger et al., 2020) At the same time, individuals dealing with somatosensory pain will also begin to feel inflammatory effects from the affected muscle area in the legs and back. Since inflammation is a body’s natural response when dealing with pain, the inflammatory cytokines can cause a cascading effect from the brain through the spinal cord, causing leg and back pain. (Matsuda, Huh, & Ji, 2019) To that point, somatosensory pain is associated with inflammation caused by normal or traumatic factors that can cause overlapping risk factors contributing to leg and back pain. Luckily, numerous treatments can reduce these overlapping risk factors caused by somatosensory pain and help restore the lower body extremities’ function.
Move Better, Live Better- Video
When the body is dealing with somatosensory pain, it can cause many individuals to think they are only dealing with one source of pain from one muscle area. Still, it can lead to multifactorial issues that affect different body locations. This is known as referred pain, where one body section deals with pain but is in a different area. Referred pain can also be combined with somato-visceral/visceral-somatic pain, where the affected muscle or organ affects one or the other, causing more pain-like issues. However, numerous treatments can reduce somatosensory pain from causing more leg and back problems. Non-surgical therapies like chiropractic care and spinal decompression can help mitigate the effects of somatosensory pain affecting the lower body extremities causing leg and back pain. These treatments allow the pain specialist to incorporate various therapeutic techniques to stretch the affected muscles and realign the spine to its original position. Many individuals can see an improvement in their mobility and daily activities as the pain-like symptoms associated with somatosensory pain are reduced. (Gose, Naguszewski, & Naguszewski, 1998) When individuals dealing with somatosensory pain start thinking about their health and wellness to ease the pain they are experiencing, they can look into non-surgical treatments as they are cost-effective, safe, and provide a positive outcome. Additionally, non-surgical treatments can be personalized to the individual’s pain and begin to see improvement after a few treatment sessions. (Saal & Saal, 1989) Check out the video above to learn more about how non-surgical treatments can be combined with other therapies to improve a person’s well-being.
Spinal Decompression Reduces Somatosenosory Pain
Now spinal decompression is a non-surgical treatment that can help reduce somatosensory pain affecting the legs and back. Since somatosensory pain correlates with the spinal cord, it can affect the lumbosacral spine and lead to back and leg pain. With spinal decompression, it utilizes gentle traction to gently pull the spine, which then can reduce the symptoms associated with somatosensory pain. Spinal decompression can help improve the somatosensory system by reducing pain and alleviating aggravated nerve root compression to relieve the legs and back. (Daniel, 2007)
Additionally, spinal decompression can be combined with other non-surgical treatments, like chiropractic, as it can help with reducing the effects of nerve entrapment and help restore the joint’s ROM (range of motion). (Kirkaldy-Willis & Cassidy, 1985) Spinal decompression can create a positive experience for many individuals dealing with leg and back pain associated with somatosensory pain while getting back their health and wellness.

Are treatments more successful when patients know key terms that describe their back pain and associated conditions?
Nerve Pain Types
When individuals need to better understand their spine diagnosis, being able to distinguish between key terms can make a significant difference in understanding the development of a personalized treatment plan. Terms that describe back pain and various associated conditions can include:
Sciatica
Radiating and Referred pain
Radiculopathy
Radiculitis
Neuropathy
Neuritis
Causes of Back Pain
Back pain symptoms are most commonly caused by the continued practice of unhealthy/poor posture and overcompensated and weakened muscles. Even for individuals that exercise regularly, the movement choices that are made throughout the day can disrupt the way the muscles, tendons, ligaments, and fascia function to maintain proper body alignment.
Injuries to, and conditions of, the structures of the spinal column like the bones, discs, and nerves, are generally more serious than posture problems and soft tissue-related pain.
Depending on the diagnosis, structural problems can cause symptoms related to nerve compression, irritation, and/or inflammation. (Michigan Medicine, 2022)
Spine and Nervous System
The peripheral nerves extend out to the extremities with sensation and movement capabilities.
Nerve roots exit the spinal canal which is part of the peripheral nervous system.
The branching of nerves from the spinal cord and exit out of the foramina occurs at every level of the spine.
Terms
There are different medical terms when getting a spine diagnosis or going through the treatment process.
Radiculopathy
Radiculopathy is an umbrella term, describing any disease process that affects a spinal nerve root and is something that’s happening to the body.
When a healthcare provider informs you that your pain is due to radiculopathy, a number of more specific diagnoses, clinical signs, and symptoms may be included as part of the description.
Common causes of radiculopathy include herniated disc/s and spinal stenosis.
Less common causes can include a synovial cyst or tumor that presses on the nerve root. (Johns Hopkins Medicine, 2023)
Radiculopathy can occur in the neck, low back, or in the thoracic area.
Often, radiculopathy is brought on by some form of compression of the nerve root.
For example, extruded material from a herniated disc can land on a nerve root, causing pressure to build.
This can cause symptoms associated with radiculopathy, including numbness, weakness, pain, or electrical sensations. (Johns Hopkins Medicine, 2023)
Even though there’s a spinal nerve root on either side of the spinal column, injury, trauma, or issues stemming from degeneration affect the nerves in an asymmetric fashion. Degenerative changes, known as normal wear and tear, typically occur in this fashion. Using the previous herniated disc example, the material that leaks from the disc structure tends to travel in one direction. When this is the case, the symptoms tend to be experienced on the side where the nerve root makes contact with the disc material, but not the other side. (American Association of Neurological Surgeons, 2023)
Radiculitis
Radiculitis is a form of radiculopathy but it is about inflammation and not compression. (Johns Hopkins Medicine, 2023)
Radicu– refers to the spinal nerve root.
The suffix – itis refers to inflammation.
The word refers to a spinal nerve root that is inflamed and/or irritated rather than compressed.
In disc herniations, it is the gel substance that contains various chemicals that is inflammatory.
When the gel substance makes contact with nerve roots, an inflammatory response is triggered. (Rothman SM, Winkelstein BA 2007)
Radiating or Referred Pain
Radiating pain follows the path of one of the peripheral nerves that transmit sensory information like heat, cold, pins and needles, and pain.
Referred pain is experienced in a different area of the body that is away from the pain source which tends to be an organ. (Murray GM., 2009)
It can be brought on by myofascial trigger points or visceral activity.
An example of referred pain is symptoms in the jaw or arm when an individual is having a heart attack. (Murray GM., 2009)
Radicular
The terms radicular pain and radiculopathy tend to get confused.
Radicular pain is a symptom of radiculopathy.
Radicular pain radiates from the spinal nerve root to either part or all the way down the limb/extremity.
However, radicular pain does not represent the complete symptoms of radiculopathy.
Radiculopathy symptoms also include numbness, weakness, or electrical sensations like pins and needles, burning, or shock that travels down the extremity. (Johns Hopkins Medicine, 2023)
Neuropathy
Neuropathy is another umbrella term that refers to any dysfunction or disease that affects the nerves.
It’s usually classified according to the cause, like diabetic neuropathy, or the location.
Neuropathy can occur anywhere in the body – including the peripheral nerves, the autonomic nerves/organ nerves, or nerves that are located inside the skull and innervate the eyes, ears, nose, etc.
Peripheral nerves are the long, thin strands that supply sensation, feeling, and movement impulses to all areas of the body located outside the central nervous system.
Piriformis syndrome is where a tight buttock/piriformis muscle constricts the sciatic nerve, which runs underneath. (Cass SP. 2015)
Chiropractic
Chiropractic adjustments, non-surgical decompression, MET, and various massage therapies can relieve symptoms, release stuck or trapped nerves and restore function. Through the treatments, the chiropractor and therapists will explain what is happening and why they are using a specific technique. Knowing a little about how the neuromusculoskeletal system operates can help the healthcare provider and the patient in developing and adjusting effective treatment strategies.

The brachial plexus is a network of nerves that begin in the cervical/neck spinal cord and travel down the cervicoaxillary canal into the armpit. Forming in the area of the shoulder joint at the branch junction of the brachial plexus, the radial nerve extends down the arm, through the elbow joint, into the forearm, across the wrist, and tips of the fingers. The nerves are susceptible to injury that can cause abnormal function leading to unusual sensations and impaired muscle function.
Radial Nerve
One of the major nerves of the upper extremity.
There is one brachial plexus on each side of the body that carries the nerves to each arm.
The radial nerve has two major functions.
One is to provide sensations in the hands, forearms, arms, and fingers.
The other is to deliver messages to muscles about when to contract.
Motor Function
The radial nerve transmits signals to the muscles of the back of the arm and forearm on when to contract.
Individuals who have abnormal radial nerve function can experience weakness of the muscles and symptoms like wrist drop.
A wrist drop occurs when the back forearm muscles cannot support the wrist, causing the individual to hold the wrist in a flexed posture.
Abnormal radial nerve function can cause symptoms of numbness or tingling in the back of the hand.
Conditions
Associated conditions to the radial nerve include lacerations, contusions, fractures, and palsies.
Nerve Contusion
A contusion typically occurs through blunt force trauma that can crush and smash the nerve area.
This causes abnormal or no function.
A nerve contusion can occur from a personal, work, or sports injury or other conditions that generate intense pressure on the nerve/s.
Nerve Lacerations
A laceration occurs when there is a penetrating injury that cuts and/or severs the nerve.
This injury can occur from stab wounds or sliced by broken glass, metal, etc.
Fractures
Broken bones of the upper extremity can lead to extended damage to the nerves near the damaged bone.
The most common type of fracture associated with radial nerve malfunction is fractures to the humerus bone.
The nerve wraps tightly around the humerus and can be injured with a fracture.
Most fracture-related radial nerve injuries heal on their own and do not require surgery.
However, the way the injury heals can be the difference between normal function and chronic pain.
Crutch Palsy
Crutch palsy is pressure on the radial nerve in the armpit resulting from using crutches incorrectly.
To use crutches properly, the individual needs to support their body weight through the hands.
However, many tend to place pressure around the armpit at the top of the crutch, causing irritation to the nerve in that area.
Padding the top of crutches and using the proper form can prevent the condition.
Saturday Night Palsy
Saturday night palsy is the abnormal function of the radial nerve after sleeping in a position that causes direct pressure against the nerve.
This often occurs when an individual falls asleep with their arm draped over an armrest on a chair.
The name comes from when individuals are intoxicated and fall asleep in a location other than the bed and in awkward positions.
Treatment
Nerve injuries often cause symptoms at different locations other than where the nerve damage is, complicating diagnosis. Determining the specific location of nerve damage is the first step in developing an appropriate treatment plan. Once the location has been identified, steps can be taken to prevent worsening damage to the nerve.
The objective is to relieve the pressure from the irritation or compression.
Massage to relax the area and increase blood circulation.
Decompression to physically restore alignment.
Adjustments to restore body balance.
Exercises and stretches to maintain treatment, strengthen the muscles, and prevent injuries.
In cases where there is structural damage, surgery may be necessary to remove pressure or repair damage.
Avoid Surgery

A nerve becomes pinched/compressed when added pressure is placed on it by surrounding structures that can include muscles, bones, ligaments, tendons, or a combination. This injures and damages the nerve causing function problems and symptoms and sensations in that area or other parts of the body that are supplied by that nerve. Medical practitioners refer to this as nerve compression or entrapment. Although compressed nerves are more commonly associated with the neck, arms, hands, elbows, and lower back, any nerve in the body can experience irritation, spasms, inflammation, and compression. The causes and treatment of a compressed nerve in the knee.
Compressed Nerve In The Knee
There’s only one nerve that goes through the knee that has an increased risk of getting compressed. It’s a branch of the sciatic nerve called the peroneal nerve. The nerve goes around the outside of the knee before traveling down the outside of the lower leg. At the bottom of the knee, it lies between the bone and skin, making it vulnerable to irritation or compression by anything that can put pressure on the outside of the knee.
Causes
Traumatic injuries over time can lead to pressure on the nerve from inside the knee. Common causes of a compressed nerve in the knee include:
Frequently Crossing Legs
Compression by the opposite knee, while the legs are crossed is the most common cause.
Knee Brace
A too-tight or strong brace can compress the leg and nerve.
Thigh-High Compression Stockings
Designed to maintain pressure on the legs, if too tight these stockings can compress the nerve.
Squatting Posture For Long Periods
This position places pressure on the side of the knee.
Fractures
A fracture of the large lower leg bone/tibia or sometimes the small bone/fibula near the knee can entrap the nerve.
Lower Leg Cast
The portion of the cast around the knee can be tight and compress the nerve.
Tell the doctor if a cast or brace feels tight or is causing numbness or pain in the leg.
Knee-High Boots
The top of a boot can land right below the knee and be too tight pinching the nerve.
Knee Ligament Injury
The nerve can become compressed due to bleeding or inflammation from an injured ligament.
Knee Surgery Complications
This is rare, but the nerve can inadvertently get pinched during knee replacement surgery or an arthroscopic procedure.
Prolonged Bed Rest
When lying down the legs tend to rotate outward and the knees flex.
In this position, the mattress can place pressure on the nerve.
Tumors or Cysts
Tumors or cysts can develop right on top or next to a nerve irritating and compressing the area.
Abdominal or Gynecologic Surgery
The equipment used to keep the legs rotated outward and the knees flexed for gynecologic and abdominal surgeries can compress the nerve.
Symptoms
The peroneal nerve supplies sensation and movement to the outside of the lower leg and the top of the foot. When compressed, it becomes inflamed, which causes the symptoms of a compressed nerve. Usually, only the lining/myelin sheath around the nerve is what gets injured. However, when the nerve gets damaged, the symptoms are similar but more severe. Common symptoms include:
Weakness that limits the ability to lift the foot toward the leg aka dorsiflexion.
This causes dragging the foot when walking.
The ability to turn the foot outward and extend the big toe is also affected.
Symptoms can be felt on the outside of the lower leg and on the top of the foot and include:
Tingling or pins and needles sensations.
Numbness.
Loss of sensation.
Pain.
Burning.
For individuals that have had a pinched nerve for two or more weeks, the muscles supplied by the nerve can begin to waste away or atrophy.
Symptoms can be intermittent or continuous depending on the cause.
The other common cause is a pinched nerve in the lumbar/lower spine.
When this is the cause, sensations, and pain will present in the lower back or the back and outside of the thigh.
Diagnosis
A doctor will look at medical history and perform an examination to make a diagnosis, determine the cause, and lay out a personalized treatment plan. The nerve in the knee can be felt as it travels around the top of the tibia, so a doctor may tap on it. If there is shooting pain down the leg, a pinched nerve may be present. Tests a doctor may order can include:
Knee X-ray
Shows any bone fractures or abnormal masses.
Knee MRI
Can confirm the diagnosis
Shows masses within the nerve.
Shows details of fractures or other problems in the bones.
Electromyogram – EMG
Tests electrical activity in the muscles.
Nerve Conduction Test
Tests the signal speed of the nerve.
Treatment
Treatment is aimed at reducing pain and improving mobility.
Over-the-Counter Pain Medication
OTC medication can reduce inflammation and improve symptoms short term.
Ice and Heat
Applying either heat or ice for 15 to 20 minutes at a time can provide relief from the symptoms.
An ice pack can make symptoms worse if it adds more pressure on the nerve.
Chiropractic and Physical Therapy
Chiropractic and physical therapy can release the compressed nerve, realign the structures, strengthen the muscles, and provide gait training.
Orthotic Boot
If walking gait is affected because the foot cannot bend, an orthotic boot can help.
This is a support that maintains the foot in a neutral position to walk normally.
Corticosteroid Injection
A corticosteroid injection can reduce inflammation and relieve pressure on the nerve.
Surgery
The nerve can suffer permanent damage if it has been pinched for a long time.
If that happens, surgery cannot repair the damage.
A doctor can perform surgery to correct a fracture, tumor, or other invasive problem causing a compressed nerve.
If conservative treatment doesn’t work, a peroneal nerve decompression procedure can be done to remove the pressure.
If surgery is needed, symptoms can disappear immediately, but it takes around four months to recover and rehabilitate.
