A condition in which the piriformis muscle contracts or spasms and places pressure on the sciatic nerve, which passes through this muscles, causing pain in the buttocks and/or along the back of the leg and into the foot. These same symptoms can be found in normal causes of Siatica. This condition is most common among women, and strangely is thought to be common among both physically active athlectic individuals (such as bikers, runners and walkers) and those who's jobs or activities involve prolonged sitting. Also See: Sacroiliac Joint Dysfunction and Siatica
A clinical diagnosis based on complaints of pain and abnormal sensations in the buttocks region with extension into the hips and posterior thigh as would be seen in sciatica.
Whereby the piriformis muscle is implicated in the irritation of the sciatic nerve, as it passes through or underneath the muscle. Often accompanied by deep buttock pain, usually in the area of the sciatic notch. Occurs more commonly in females.
Pain in the buttocks resulting from a tight piriformis muscle pressing against the sciatic nerve; can be treated by stretching exercises for the buttocks
A condition caused by the sciatic nerve getting pinched as it exits the spinal column. (Sometimes, it can mimic the symptoms of sciatica.) The pinching is sometimes caused by muscles spasms. Piriformis syndrome sometimes causes pain along the back of the thigh to the knee, or loss of feeling in the soles of the feet.
Piriformis syndrome is a neuromuscular disorder that occurs when the sciatic nerve is compressed or otherwise irritated by the piriformis muscle. This causes pain, tingling and numbness in the buttocks and along the course of the sciatic nerve. The syndrome may result from anatomical variations in the muscle-nerve relationship, or from overuse or strain.
