What's with guys and shoulders? This: The mind says "Do it", body says "Can't!"
Problem with shoulders is that there aren't any nerves in the places that tear, so you never feel it -- there is no pain before it breaks or tears, and no pain when it happens. In fact, I don't know exactly when it occurred. But it sure hurt like crazy afterward. On the left shoulder two years ago, there was no afterward pain either. It just really hurt to try to lift anything over my head.
I'll probably need surgery, but since the healing process is continuing, I'm going to wait and see. If it gets better to the point that it doesn't bother me, and I can do most things without any problems, then I'll put it off indefinitely.
