Piriformis syndrome is a condition of neuromuscular disorder in which the sciatic nerve becomes irritated by the piriformis muscle. Amongst other symptoms, this brings on pain in the buttocks and referred pain along the sciatic nerve (sciatica).
piriformis syndrome symptoms
Although symptoms of piriformis syndrome may vary from one case to the next, some potential symptoms of the condition may include the following. Symptoms indicated refer to the location of the buttocks or sciatic nerve unless otherwise mentioned.

piriformis syndrome causes
Medically, the sciatica symptoms involved in piriformis syndrome are brought on by irritation of the sciatic nerve. It is not known why the piriformis muscle begins to irritate the sciatic nerve at certain times.
Piriformis syndrome is commonly associated with falling-type injuries. It is also thought that overpronation of the foot may lead to piriformis syndrome as the piriformis muscle can become tight (due to extra use).
