I have MS, but recently I have been having Joint Pain as well my knees hurt my shoulders hurt my thumb hurts. My neurologist says that it is arthritis. I am like geesh I am only 31. My real issue right now is that my left his is driving me insane it feels out of socket and I am noticing that now 1 leg is longer than the other. What exercise or what should I do to "pop" it back into place
