But I'm not sure he's right. From what I've read about this condition, I would expect my shoulder to hurt all the time. It doesn't. It hurts when I move my arm up or out, but not if I move my arm so that my hand is toward my head instead of out and away from my head. If I'm careful, or if I stretch the muscle first, I can even reach up or out without too much pain. The problem is that I don't always remember to stretch the muscle first--and stretching doesn't *always* work. Also, sometimes it feels as if the ball is slipping out of the socket in my shoulder. (I forgot to tell the doctor this, which may be relevant to the diagnosis.) I also seem to get pain in my elbow when I reach the wrong way. I spend a lot of time at the computer, and I use a mouse a lot when I'm working on my music. I understand that this can cause or at least aggravate rotator cuff tendinitis. So maybe my doctor is right. I seem to recall a message from somebody on this board who said she(?) either had rotator cuff surgery or was going to have it. Was that related to fibromyalgia in some way? I was wondering whether anybody else has experienced rotator cuff problems. --Laur R.M.
