Disease at a Glance

Piriformis syndrome is a rare neuromuscular condition that occurs when the piriformis muscle in the buttocks presses on the sciatic nerve. The condition is primarily associated with sciatica; however, other symptoms may include tenderness, aching, tingling and/or numbness of the buttock and pain when sitting for a long period of time, climbing stairs, walking or running. Piriformis syndrome is caused by damage, irritation or overuse of the piriformis muscle which can make the muscle swell or tighten. This puts pressure on the nerve beneath it (the sciatic nerve) which leads to the signs and symptoms of the condition.
