Before surgery...the muscles in my upper right arm, should and neck were in a constant state of contraction. After the surgery and right up until this morning...no contractions or pain at all in the right arm....now I keep having twinges that I think are the muscles contracting again. It's a twinge with a sharp pain in the arm/ bicep area. Is that normal do you think? Sometimes I wonder to if they steroids they give during the surgery don't temporarily calm things down. I know the steroid shots worked for a few weeks pre-surgery so just wondering if things are wearing off now.
