Piriformis Syndrome

OK, so I’ve hinted at my opinion already in the title. I am skeptical of piriformis syndrome (PS). I think it is a rare condition. When the concept was first birthed, it was based on the idea that there are causes of sciatica other than a herniated disc. At the time, within standard medical thinking this was an advance. I am using the term sciaticaloosely, the way patients use it: any pain or abnormal sensation in the buttock, hamstring or posterior leg.
