Damage To Piriformis Does Anyone Know About Piriformis Syndrome?

Does anyone know about piriformis syndrome? - damage to piriformis

I have a neurologist in sports medicine doctors, one who told me that nerve damage in my area were piriform HAV. I also saw many orthopedists. Nobody can tell me why my band appears above my hip, and why so much pain. Does anyone know a doctor in this region that concentrates its practice in this area?
