I recently had a cortisone shot in my shoulder for rotator cuff tendinitis. It is still hurting 4 weeks later. particularly in the morning. Before the shot, my arm had some stiffness, but no pain. The doctor insisted on giving me the shot even though I didn t want it, and didn t offer any other treatment. Now I have pain at the injection site and in arm and shoulder muscles for 4 weeks. I am worse off now. And upset about this. Did the doctor mess up? What can I do for this? I am taking physical therapy but it is not helping much. I feel like the shot injured me !
