Ask Dr. Rob about piriformis syndrome
Common condition is the original pain in the buttocks
What is it?
Piriformis syndrome is a painful condition that develops due to irritation or compression of the sciatic nerve near the piriformis muscle. The piriformis muscle connects the lowermost vertebrae with the upper part of the leg after traveling the "sciatic notch," the opening in the pelvic bone that allows the sciatic nerve to travel into the leg. Here, the muscle and nerve are adjacent and this proximity is why trouble can develop.
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.
