Do you know your piriformis muscle?
The piriformis is small but powerful, a muscle located deep within the buttock that connects between the lower spine and the beginning of the femur. It’s function is to assist in rotation of the hip, but the piriformis is more well known for the problems it causes than for the way it assists your day to day movement. The problem is location: it just happens to sit right on top of the sciatic nerve, the longest nerve in the human body . In fact, in some people’s bodies, the nerve runs directly through the muscle. This sets up a scenario for impingement on the sciatic nerve.
