My husband, who is 40 years old, with no injuries, has been having severe pain in his left arm with swelling. The pain runs from his elbow to his fingers and he has been dealing with this every day for the last year. He has seen several doctors, been prescribed pain medicine and steroids. Nothing is helping. He has also had several nerve tests done and all have come back showing no nerve damage. Some days are worst than others because of the swelling but the pain is there all of the time. He was told to minimize the use of his arm and to wear an elbow brace but that does not help either. Any ideas or suggestions on what we should do now?
