Colleen, my ortho did a MRI and X-ray and diagnosed this as Osteoarthritis, however I had a diagnosis many years ago that I had piriformis syndrome and I’m convinced it’s back. I just don’t have a lot of faith in these doctors where I am. My ortho wants to replace my hip. I don’t want to do something that is not necessary, I need to get this piriformis bug out of my head first. I need a piriformis specialist to diagnose that I don’t have it. That’s when I’ll be content and do hip surgery. I’ve found that the ortho’s here do not really believe in the piriformis being an issue.
