Piriformis syndrome is a painful condition that develops due to irritation or compression of the sciatic nerve near the piriformis muscle.

The condition is relatively common. Estimates suggest that about 5% of cases of sciatica (irritation of the sciatic nerve causing radiating pain from the back or buttock into the leg, calf and foot) are due to piriformis syndrome. It seems to be more common among women though the reason for this is not known.
