I slept on my arm about a year ago and the pain was so severe that I could barely raise the arm, pain radiating from back, neck, down arm. Eventually, it went away, and is back with a vengeance. I can t reach for anything and when typing, feel it in my bicep and shoulder blade. I am taking ibuprofen and sleeping with pillow under my arm, but have to get the right position or it hurts terribly. Help, please.
