Re: rotator cuff tendinitis - ouch
I had bicep tendinitis and I could not move my arm at all for the pain. The way my doctor new what it was by getting to move me arm in certain ways. If one movement was painful then it was something, if a different movement was painful then it was something else. But try and keep your shoulder moving by doing those exercises that your doctor gave you. I didn't and it started to freeze up and that was more pain for then the tendinitis.
