You may also want to see an orthopedic hip specialist who can do X-ray/MRI of soft tissues in pelvis/hips/hamstring connections. Depending on what they find, they can do physical therapy, cortisone injections, and surgery if needed. I may need my right hamstring tear surgically debriefed and reattached because it has t healed in over a year after rest/therapy.
