Since one of my original nerve injuries that led to my crps started with my ulnar nerve in my left arm.....I know how badly that can hurt! Especially since I also had an EMG done about a month after I also know how painful that can be in top of the injured nerve and crps!! Make sure you keep in close contact with your PM doc and that they cover any extra pain or flares with the proper meds! I hope you can get through it with as little pain as possible although I know it's not likely!! Know we are here for you!!!#
