"i have been taking morphine for about 4 years now. i presently take 60mgs (of the slow release morphine) twice daily. i have chronic shoulder pain in both shoulders from 8 surgeries in the left for a torn rotator cuff, which they can&#039;t do anything about. the right shoulder has had 1 surgery for the same problem. got the same result for it, they cant do anything for it. the morphine helps me with some pain. i could just imagine how much it would hurt without it.
