my friend has a calcium buildup in his shoulder. And he is hurting really bad. He has been to a doctor and they gave him a shot in the shoulder. It eased up, but now it has started back to hurting again. What can be done to stop the pain. And it is also swallon.
Hello.  If your friend hasn't had a MRI scan of the shoulder he needs one to check for tendonitis or a tear of a rotator cuff tendon, and he may need arthroscopic surgery to repair the problem he's having.
