Back injuries from vehicle collisions vary from person to person. Common injuries may include strains, sprains, herniated discs, and fractures, and individuals dealing with certain spinal conditions like spinal stenosis may cause the medical condition to accelerate. Still, the force and physical impact the body absorbs during a crash, no matter how minor the accident or how safe the car is, will cause bodily aches and pains with the potential for other spinal conditions. Chiropractic care, massage, decompression, and traction therapy can relieve symptoms and restore mobility and function.
Back Injuries From Vehicle Collisions
Depending on how the impact affects the spine, problems can present in various areas of the back. The violent motion can sprain, strain, and fracture spinal components. Even minor incidents can impact mobility. Symptoms can stem from inflammation, compressed nerves, or fractures. Any damage can have long-lasting effects on the vertebrae, nerve roots, and back muscles. A vehicle collision can affect the following:
Lumbar vertebrae – lower back
Thoracic vertebrae – middle/upper back
Cervical vertebrae – neck
Each area consists of bones, tissues, muscles, nerves, tendons, and ligaments extending from the neck to the pelvis.
The most common back injuries are to the neck and lower back, where the most movement and shifting occurs, often causing nerve damage.
The central placement and rigid structure make middle back injuries less common.
Upper back injuries that connect the rib and chest region can affect breathing.
Soft tissue injuries might not show up immediately.
Symptoms
After a vehicle collision, it’s common to feel sore all over. The symptoms can range from manageable discomfort to complete immobility. Individuals may experience the following:
Muscle spasms
The muscle may repeatedly twitch, feel like hard knots, and feel tender to the touch.
Muscle spasms can vary in pain levels from mild to debilitating.
Stiffness
Individuals may not feel as flexible because of the muscle tension that activated during the crash to protect the body.
Stiffness can go away after light stretching or continue throughout the day.
Burning or Shooting Pain
A burning or shooting pain may travel down the back and buttocks through the back of one or both legs.
It can be mild, dull aches and pains that go away quickly or last for days.
Changing positions, such as sitting up after waking up or standing up after sitting, can cause sharp acute pain.
Certain physical activities can cause a throbbing sensation or mild pain when attempting to perform various tasks.
Tingling and/or Numbness
Tense muscles can pinch nerves leading to sensations of tingling or numbness in the legs, feet, arms, or hands.
Head Issues
Headaches, dizziness, or disorientation can present.
Spinal Disorders
Back injuries from vehicle collisions can result in a degenerative disc disorder months or years later. It can also speed up health issues individuals didn’t know they had before the crash. As the body ages, previous damage combined with degeneration can result in:
Micro-tears within the muscles and ligaments are common and cannot be found through a standard x-ray.
Spinal adjustments can bring the spine back into alignment, producing natural anti-inflammatory properties to assist with discomfort and heal the tears.
Scar Tissue Breakdown
Muscles can get scarred, causing stiffness and soreness.
Chiropractic massage targets these areas and breaks down the build-up quicker than if it was left to heal on its own.
Less scar tissue means faster recovery.
Range of Motion and Mobility Restored
Back injuries can result in restricted mobility.
It may be difficult to turn or move when the muscles are inflamed.
Mobilizing the spine through adjustments restores the proper range of motion.
Decreased Medication Use
Prescription pain medications can turn into dependency.
Chiropractic adjustments can ensure that the injury is healed and the pain is not just masked.
Long-Term Benefits
Receiving chiropractic care can help prevent minor injuries from worsening into serious and chronic conditions.

T-bone accidents/collisions, also known as side-impact or broadside collisions where the front end of one car slams into the side of another, can result in severe injuries and tend to have a more devastating effect on the body. Side impact collisions account for 24% of driver or passenger deaths; even at 30 mph, side-impacts regularly cause injuries to the occupants of the struck car. Modern vehicles have many safety features, including safety belt features, airbags, and collision avoidance systems that protect drivers and passengers from front and rear collisions; however, when it comes to side-impact, occupants tend to remain unprotected.
T-Bone Side Collision Causes
T-bone accidents usually happen at intersections. Usual Causes of T-bone accidents involve someone failing to yield the right of way. The most common causes include:
A driver makes a risky left turn at an intersection, believing the other car/s will stop.
A driver decides to run a red light crashing into a vehicle making a left turn.
A driver runs through a stop sign, slams into a vehicle, or gets slammed.
Back injuries can damage the spinal cord causing herniated discs, sciatica, and chronic pain that can radiate to the rest of the body.
Treatment and Recovery
Individuals have different recovery times and depend on the severity of the injury and on any pre-existing conditions. Brain injuries and spinal issues can take months to recover fully. Fractures placed in a hard or soft cast to heal for weeks or months can lead to muscle atrophy. Chiropractic therapeutic massage and decompression strengthens muscle weakness, resets and realigns the spinal column, improves range of motion/movement, strengthens grip, and relieves pain.

Motor vehicle crashes and accidents cause significant trauma in a few seconds changing an individual’s life completely. Severe injuries include traumatic brain injury, spinal cord damage, fractures, and amputations. Many individuals experience post-traumatic stress disorder – PTSD after a vehicle collision; even a minor accident can cause emotional trauma symptoms. PTSD commonly presents with other symptoms that range from depression to heart disease, and the most frequent symptom is physical pain. Chiropractic decompression, physical therapy, and therapeutic massage can help alleviate physical pain.
PTSD Physical Pain
Physical trauma can cause immediate physical effects and injury, as well as physical symptoms that present later on.
Trying not to talk or think about the crash or accident with friends, family, places, or anything associated with the trauma.
Avoiding activities.
Emotional numbness.
Detachment.
All can generate physical muscle tension and chronic stress, leading to headaches, migraines, back pain, stomach pain, and body aches. Long-term physical pain symptoms can turn chronic pain and medication dependency into a vicious cycle.
Chiropractic Therapy
Chiropractic care diagnoses and treats disorders of the musculoskeletal system. Chiropractic treatment is recommended to help alleviate the physical symptoms of PTSD. Trauma causes individuals to store intense emotions in their bodies. Chiropractic manipulation and decompression release the tension in the muscles caused by the trauma and the emotional stress. Adjustments restore the body’s alignment and open the nervous system circulation, allowing signals to flow freely, leading to a healthier mind-body connection.

The gut microbiome is “the second brain” in the body as it helps regulate homeostasis and metabolize the immune system for functionality and to keep the body in motion. The brain is part of the nervous system, providing neuron signals constantly traveling all over the body. The brain and the gut have a communication partnership where they send information back and forth for the body to function normally. When the body gets injured, either the brain, the gut, or both can be affected, causing dysfunction and unwanted symptoms that can cause other issues to affect the other systems in the body. One of these injuries can affect the brain in a traumatic way, which can disturb the signaling to the gut microbiota and affect an individual’s quality of life. Today’s article looks at a traumatic brain injury known as a concussion, its symptoms, and how it affects the gut-brain axis in the body. Refer patients to certified, skilled providers specializing in gut treatments for individuals that suffered from concussions. We guide our patients by referring to our associated medical providers based on their examination when it’s appropriate. We find that education is critical for asking insightful questions to our providers. Dr. Alex Jimenez DC provides this information as an educational service only. Disclaimer
Can my insurance cover it? Yes, it may. If you are uncertain, here is the link to all the insurance providers we cover. If you have any questions or concerns, please call Dr. Jimenez at 915-850-0900.
What Is A Concussion?
Have you been headaches that pop out of nowhere and affect you daily? Have you been experiencing leaky gut or other gut disorder issues causing problems? Do you have trouble concentrating on the simple tasks at hand? Many of these symptoms are signs that you might be suffering from a concussion. Research studies have defined a concussion as a transient disturbance that traumatically induces brain function in the body. Concussions can vary depending on the severity of the injury. When a person suffers from a concussion, the neurotransmitters get disrupted as the brain’s electrolytes go through neurological dysfunction, and blood glucose metabolism decreases cerebral blood flow. Other research studies have found that a concussion does an axial rotation to the brain, which results in the brain jiggling and causes whiplash to the neck. This disruption will cause a biochemical injury that either alters the blood glucose metabolism or can cause derangement of the adenine nucleotides of the nervous system.
Its Symptoms
Research studies have found that when a person suffers from a concussion, the symptoms in its acute phase can drastically change and evolve into a chronic situation over time. Concussions usually occur in individuals that play a contact sport, where they bump each other in the heads, auto accidents that causes severe injuries that affect the neck and brain, or even a simple blow to the head. Other research studies have stated that the symptoms of a concussion can include:
Blurry vision
Headaches
Dizzyness
Mood changes
Light sensitivity
Concentration and memory complications
Additional research studies have mentioned that neuronal dysfunction can occur when a person suffers from a concussion as there are ionic shifts, impaired connectivity to the brain, and changes in the neurotransmitters from completing their jobs to provide sensory-motor functions to the entire body. When this happens, not only does the nervous system gets affected, but the gut system gets affected as well.
An Overview Of Leaky Gut & Concussions-Video
Do gut disorder symptoms seem to be affecting your quality of life? Have you become sensitive to light? Have you felt muscle stiffness in your neck? Or have you been suffering from frequent headaches? If you are experiencing any of these symptoms, it might be due to a concussion affecting your gut microbiota. The video above explains how a concussion and a leaky gut are linked. In an average functioning body, the gut and the brain have a bi-directional connection as they help send the neuron signals to each of the body systems and muscle tissues that make the body move. When traumatic forces like a concussion affect the brain, it can disrupt and change the neurotransmitters signals that can cause gut disorders in the microbiota. When gut disorders affect the gut microbiota, it can cascade a series of inflammatory effects that can affect the body’s homeostasis and immune function. Experiencing these symptoms in the body can drastically affect a person’s mood and quality of life if it is not taken care of immediately.
How The Gut-Brain Axis Is Affected By A Concussion?
Since the gut-brain axis has a communication partnership, this axis helps the body’s immunity, homeostasis, and metabolism function. When a concussion starts to affect the gut-brain axis, research studies have shown that the communication pathways are affected in the gut-brain axis as tit incorporates the afferent and efferent signals. The signals involved in the gut-brain axis include the hormones, neurons, and immune pathways that can result in chronic gastrointestinal dysfunction and disability to the body. Since the gut helps keep the body functional through homeostasis, the brain helps the neuron signals provide sensory functions. With a concussion, these signals are disrupted, affecting the body’s functionality and causing a change in a person’s mood.
Conclusion
Overall the gut-brain axis provides functionality to the body by maintaining the homeostasis and metabolism of the immune system. A person’s involvement in a traumatic accident can lead to brain injuries like a concussion that can impair the gut and brain relationship. A concussion can become severe when it is not treated right away and can affect a person’s quality of life in their health and wellness journey.

When the body goes through intense trauma like a car, truck, crash, or accident, the trauma can slip, bulge, herniate, or rupture the spinal fluid-filled discs that can extrude from the disc space, causing the nucleus pulposusto tear through the annulus fibrosus and compress the nerve roots causing pain. Depending on the severity and force of the crash or accident, a herniated disc can cause the vertebrae to push into the spinal canal, where it can compress, irritate, and/or injure the spinal cord, which can lead to other health issues. Nerve impingement from a herniated disc can also cause numbness and tingling in the hands, arms, legs, and feet. A chiropractic spine disc herniation decompression treatment plan can heal the herniation, realign the spine, stretch the muscles and joints, and rehabilitate the body back to top form.
Spine Disc Herniation
Symptoms of Herniation
Signs and symptoms depend on the spinal area and whether the disc is rubbing or compressing a nerve. Pain is often described as a sharp or burning sensation. A herniated disc usually affects one side of the body.
Pain Presents When Sitting Down – sitting causes a significant strain on the lower spinal discs. When sitting, the pain experienced can worsen.
Arm or leg pain – Depending on the herniated disc, pain can spread to other surrounding areas.
For a lower herniation, this could be the buttock, thigh, calf, and foot.
For a herniated disc in the neck region, pain can be felt in the shoulder and arm.
Pain can present in the arm or leg when coughing, sneezing, or moving into certain positions.
Numbness or tingling – presents from the compressed nerves and spreads as the average blood/energy flow is disrupted.
Muscle Weakness – the affected nerves that support the spinal muscles can lose normal strength causing awkward postures and fatigue.
A herniated disc can be present without symptoms – individuals won’t know unless spinal imaging is ordered.
Sciatica Sensations – the damaged nerve roots affect the ability to function correctly and can cause burning pain, numbness, weakness, and tingling along the front and/or back of the thigh, leg, and/or foot. This can result from direct compression or chemical irritation from a leaked out herniated disc that causes inflammation around the nerve root area.
Chiropractic Injury Care
When a disc herniates, it inhibits the body from communicating and healing itself. To activate proper communication from the brain to the rest of the body, chiropractors perform spine disc herniation decompression which clears the neural system and opens the lines of communication.
Spine Disc Herniation Decompression
Nonsurgical spinal decompression gently stretches the spine to relieve pressure and heal the herniated disc. It is a safe procedure considered a natural alternative compared to surgery or pharmaceutical approaches. Spinal decompression therapy:
It is safe for all ages
It is non-invasive
Sessions take between 30 to 45 minutes, depending on the individual and the injury that could require multiple sessions.
Offers a quicker recovery time
It is performed on a computer-controlled table customized to the individual’s specific needs and injuries.
A treatment plan can expedite the recovery process, rehabilitate and strengthen the whole body, and help avoid minimally invasive spine surgery.

Automobile accidents and crashes can cause all kinds of damage to the body even when the accident/crash is not severe. Physical symptoms might not present at all for several days, even weeks. This is known as having delayed injury symptoms. These can include:
Swelling.
Stiffness.
Aching.
Pain that radiates all over the body.
Sleep problems.
Headaches.
Brain fog.
Disorientation.
Memory problems.
Chiropractic and physical therapy rehabilitation can restore the body’s alignment, stop inflammation, loosen, stretch and strengthen the musculoskeletal system restoring optimal health.
Adrenaline
When the body is involved in a dangerous physical situation, it protects itself by releasing a surge of adrenaline. This hormone protects the body, causing the fight or flight response when in danger. Adrenaline causes several preservation responses that include:
Intense increase in energy.
Little or no pain.
Enlarged blood vessels and airways increase oxygen flow.
Increased strength from increased blood flow to the muscles.
Changes in vision and hearing that focus on sights and sounds all around.
Endorphins are released that make the body feel calm and in control.
Endorphins affect the way the body responds to pain and stress.
Individuals don’t start feeling aches and pains until the adrenaline and endorphins wear off. However, because everybody is different and the emergency response has turned off, the body still might not feel the injury symptoms. These are delayed injury symptoms.
Rate of Speed
When riding in a vehicle, the body moves at the same speed as the vehicle. During an impact, the vehicle stops, but the body continues moving until it stops, typically with a lot of force from the seatbelt, airbag, or other barriers. The intense momentum change can cause soft tissue damage and ligament or muscle strains from the stretching, pulling, contracting, and tearing. Also, the intervertebral discs can tear, bulge, or herniate over time, creating pressure on nerves and the surrounding tissues.
Delayed Injury Symptoms
Headaches
Headaches that develop days after an accident/crash are common.
They can signal a possible injury to the neck or head, a blood clot on the brain, or a concussion.
Back pain can be caused by injury to the muscles, ligaments, nerves, or damage to the vertebrae.
Low back pain occurs in more than half of rear-impact collisions and almost three-quarters of side-impact crashes.
Chiropractic Rehabilitation
After an accident, soft tissues can sustain minimal damage; however, the minimal damage left untreated can start to worsen and turn into a painful condition. Emergency room visits are to rule out major injuries like brain/nerve injuries, bleeding, punctures, lacerated organs, fractures that require emergency stabilization. Chiropractors look for other symptoms and mechanisms that indicate damage to the body’s soft tissues and nerves to see if they have been stretched or torn and dysfunction in the nervous system.
Body Composition
Calorie Counting
Counting calories can be a stepping stone to change behavior towards food. Tracking what foods are being taken into the body promotes mindfulness of dietary habits. Studies on the subject reveal a significant association between self-monitoring and weight loss. Takeaways include:
Take small steps by saying no to second portions during dinner or take a healthy sweet snack or piece of fruit instead of a pastry, cookie, etc.
Try to start making a habit of eating less processed foods.
Meals high in protein and fiber are generally more filling, making the body feel fuller from fewer calories.
The more attention there is to the food choices, the more likely reexamination occurs.

Tractor-trailer semi-trucks are a vital part of our transportation/supply system. However, weather, drivers that are not careful and/or well-trained can cause dangerous and sometimes fatal accidents. One type of accident resulting from truck driver negligence is the jackknife accident. Jackknife accidents are extremely catastrophic because they can involve numerous vehicles. Almost all of them involve life-altering or fatal injuries. Here’s what to know about these violent truck crashes.
Jackknife Collision
A jackknife occurs when the trailer of semi-truck swings to one side at a 90-degree angle and uncontrollably overtakes other lanes of traffic.The term comes from the look of the tractor-trailer after the crash resembling a jackknife or the letter L. When a jackknife wreck happens, the trailer and cab can hit and crush other vehicles in its path. It can also block numerous lanes leading to additional collisions. Jackknife crashes can also be considered rollover crashes when the truck slides and rolls over onto its side, although not all rollovers end in a jackknife.
Causes
Jackknife collisions are often either the cause of driver negligence or inclement weather, other distracted drivers, truck maintenance, or a combination. These include the following:
Excessive Speed
If a truck driver is speeding, the trailer can slide sideways and jackknife when forced to stop too quickly.
The average tractor-trailer weighs about 80,000 pounds.
The average length of a trailer is between 70 – 80 feet.
Tractor-trailer trucks need 40% more time to brake.
Weather Conditions
If drivers do not take it slow enough, bad weather or road conditions can also cause a jackknife.
Ice, snow, rain, loose gravel, or loose asphalt can cause trailers to bounce and slide.
Hazardous road conditions, as accumulated oil can cause slipperiness.
Improper Following Distance
Truck drivers that do not provide an adequate following distance to allow for a safe stopping distance can cause the trailer to slide sideways and jackknife when having to slam on the brakes.
Drivers who do not exercise caution as they enter and properly maneuver down hills or curves can end up shifting out of position and possibly topple over.
Driver Operator Fatigue
Many tractor-trailer accidents/crashes happen when drivers have logged too many hours without proper rest.
When the body is tired, response time suffers.
If a driver is groggy, they lack the cognizance to maneuver out of a dangerous situation.
Inexperienced or Untrained Operators
Driving a truck is a demanding job that requires several skill sets and experience.
Truck companies try to lower costs by using inexperienced drivers that don’t have the training or experience for long hauls or driving on busy/dangerous highways and interstates.
Load Balance
Safe truck driving ensures the trailer’s cargo is loaded correctly and the weight is equally distributed.
When the load is unbalanced, it can shift, causing the trailer to tilt or tip.
Unbalanced loads are a common factor in rollover crashes.
Lack of Maintenance
Drivers or companies that ignore:
Routine maintenance
Alignment checks
Brake pad replacement
All can lead to accidents and crashes.
Research shows that jackknife crashes can cause widespread damage, as they usually spread across multiple lanes of traffic. Because of this, there is the danger of secondary crashes or vehicles not initially involved in the crash, running into the tractor, trailer, or scattered wreckage and debris.
