Information: Piriformis Syndrome and Sciatica Anatomy

   

This drawing illustrates the important anatomy for piriformis syndrome.

The nerve-related leg pain of Sciatica is often due to piriformis muscle syndrome. Unlike the sciatica from a herniated disk, there is often little or no back pain while buttock pain predominates. The pain is worse when sitting, relieved by standing or walking, and often extends no farther down the leg than the ankle or mid-foot. When toes are involved, it usually affects all five toes.

This drawing illustrates the important anatomy for piriformis syndrome and shows how certain leg positions pull the piriformis muscle up against the sciatic nerve causing buttock pain and radiating leg pain.
