Piriformis syndrome is a rare disorder of the nerves and muscles. When you have it, your piriformis muscle--a flat, band-like muscle located in your butt near the top of your hip joint--presses on the sciatic nerve. Your piriformis muscle is important for lower body movement. It stabilizes your hip joint and lifts and rotates your thigh away from the body. This is how you're able to walk, shift your weight from one foot to another, and maintain balance.
