OUCH!!! What do you mean by disability? Forever? I don't think so. I had something less than a Rotator Cuff problem and needed an operation on it. I was on disability, but after three months, my arm was back to "normal" A RC surgery is a lot worse and you could be out longer, or if the doctor effed up with the surgery, you possibly could get partial disability, but complete disability.....forever? If you get it I want your lawyers name.
