I slipped on a flight of stairs banged my forearm pretty. Bruised immediately and scratched up from elbow to middle of forearm. Had pins and needles in fingers Went to urgent care on broken bones. and then orthopedist the next day to be sure. It was splinted once the splint came off it started to itch and when getting the X-rays too. Bruised my ulnar nerve pretty bad. Dr said, it will just take time to heal. It has been five days now bruising is changing color which is normal but it has been itching,hivy and becoming a rash now. The rash hurts so much which caused more pain to the nerve. Why is this happening? What can I do to stop it
