I have lost over 50% use of the arm and shoulder and have not gotten a good nights sleep in months. The pain has gone into my neck and cortizone shots have not helped. I have had MRI, x-rays, physical therapy, seen a chrioprator, use ice and heat, advil and muscle relaxers. Anyone that can help me or give me other advice? I am sick of doctors and sick of the pain and I can not help but wonder why this is still bothering me.
