I have been having trouble with my left arm for about
a year. The pain got so bad I would have welcomed an amputation. I went to the Dr., they couldn't do anything. Went to a massage therapist, helped, then went to a chiropractor. He took an ex-ray and the curvature of my neck was gone causing pinched nerves. After several treatments with him and continued massage therapy and doing my prescribed physical therapy, the pain is gone most of the time. Still having a lot of neck stiffness and pain though.
When I went back to the Dr. a couple months ago (when he diagnosed me with FM) he said the loss of curvature in the neck was due to the FM, so I will probably be doing therapy for this the rest of my life.
