... epideral and is doing great other than this HORRIBLE pain in the top on the left arm. This is the arm that the IV was in during her hospital stay. She is in tears. The pain meds are NOT helping with this at all. She said it feels like a tooth ache but in her arm and is worst than any pain she has ever had. It is in the muscle / bone in the top of her arm. Could this be a side effect from the epideral or the IV??? Please help. Her Doctor doesn't seem to have a clue. It hurts to lift her left arm and it hurts to try and put any pressure on her hand as if she is trying to use her hand to help push herself up. Any help would be appreciated.
