Ditto on the 'be patient' bits from everyone else. Mine was the result of a ski injury that was initially diagnosed as only mcl damage. My PT was frustrated that I was still experiencing pain and not progressing like I should have after weeks. So off to the MRI machine I went. The MRI found a fracture, acl damage and the bone bruise. Didn't change the PT regimine a bit, just got me more of it for longer with a little more patience.
