Swelling, inflammation and spasm can occur in the piriformis muscle due to trauma, prolonged sitting or repetitive injury such as from sports. The pain may run down the back of the thigh.

How is Piriformis Sydrome diagnosed?

There is no direct, definitive test for Piriformis Syndrome. It is diagnosed by history and physical exam. Imaging may be ordered to rule out other pathologies.
