I injured my piriformis last year trying to do deadlifts for a charity fundraiser. (UG!!) I tried everything -- painkillers, massage, acupuncture, traumeel injections, gabapentin, physical therapy, exorcisms (!), etc etc etc.

It eventually went away and the worst part was how I don't know which of all the things fixed it, or if it just healed on its own. BODIES, AMMIRITE??
