Im amazed at what a little time off my feet had done to my legs. Surgery can mess you up faster than I would have thought. I had back surgery, actually 3 of them since early September. I was off my feet so much that my ligaments/tendons/muscles have gotten extremely tight. I cant straighten out me legs and my toes have actually curled up. Its getting better slowly but its amazing how fast it goes bad. Im sure your shoulder will get better with time. The key seems to be pushing it to the edge of pain w/o going past. If its inflamation, ask your Doc to put you on Indomethacin (Indocin) for awhile. Its a very strong anti-imflamitory.
