I have been having elbow pain for most of the past 5 months. It was originally diagnosed as tennis elbow and I went to physical therapy for a couple of weeks. It improved somewhat but did not completely go away. About a month later I had a cortisone shot that resulted in marked improvement; however, after 2-3 weeks the pain returned. It has done nothing since except get worse. It is difficult to pick up anything with my right hand and/or use it too much for anything. Could it still be the tennis elbow or are there other possibilities?
