I had fallen in my bedroom causing a massive tear in my left rotator cuff. It was so severe that it could be repaired, necessitating a complete shoulder replacement done masterfully by Dr. Warren. Initially I had little pain, but that changed after the anesthetic wore off,and I had some pain medication at home. Thereafter, Dr. Warren had me begin a six week course of outside physical therapy. On the days I did not have PT, I did similar exercises at home. Gradually, the pain wore off. I have about 80 percent of my right shoulder.
