Sciatica is identified as a group of symptoms occurring when the sciatic nerve, found on the lumbar region of the spine, becomes irritated. The most commonly diagnosed cause of sciatic nerve irritation, or sciatica, results due to compression or impingement of a single or multiple nerve roots caused by natural spinal degeneration with age or a disc herniation in the lower back, which may occur after trauma from an injury. The symptoms of sciatica generally originate in the area of the buttock, and depending on the grade of the underlying nerve compression and inflammation, sciatic nerve irritation may radiate down the entire leg into the ankle and foot.
Piriformis syndrome is a condition in which the piriformis muscle, found in the buttock region from the upper femur bone to the edge of the sacrum, or the pelvic bone below the lumbar spine, contracts and spasms causing pain and tightness as well as tingling and numbness. The symptoms of piriformis syndrome are very similar and are often closely associated with sciatica. In some cases, the condition actually causes sciatic nerve irritation. Because the sciatic nerve runs underneath or through the middle of the piriformis muscle, contraction or inflammation of the tissues in this area may compress the sciatic nerve and develop sciatica symptoms. This is one of the main reasons sciatica and piriformis syndrome are often misdiagnosed.
As previously mentioned, the symptoms of sciatica and piriformis syndrome are very similar. Both cause pain, tingling and burning sensations, and/or numbness down the affected leg which can radiate down into the foot. Furthermore, this set of symptoms and the condition tend to closely correlate to biomechanical functional complications in the joints of the back and pelvis. Sciatica and piriformis syndrome may even be present simultaneously in the same person which can make telling both complications apart more difficult.
While sciatica is a term used to describe a set of symptoms affecting on the lumbar region of the spine, sciatic nerve pain can occur due to a variety of injuries or conditions. Piriformis syndrome, a condition affecting the piriformis muscle located in the buttocks, can cause symptoms similar to sciatic nerve pain, where these two complications may be often confused.
