I had a hamstring tear and had difficulty sitting and doing my fun activities. I have been seeing my non-orthopedic doctor and after a time, was referred to the ortho surgeon who specializes in the "butt" issues that come. I had a tendon repair and debridement. There was a good bit of "stuff" removed. Post recovery, much better. I can sit (probably more than I should) and enjoying new activities. I had the surgery at 62, so it might be a way to go. Do the rehab, stay active and listen to and follow directions.
