my fiance has a tramatic brachial plexus injury in his left arm. he went to the doctor yesterday and she suggested back surgery to "fuse discs" his main problem is his right shoulder is carrying all the weight. when he got the injury it also crushed his shoulder. he has been through surgery after surgery including 2 nerve transplant surgeries. i was just curious if back surgery is neccessary. he is taking tremadol & 10-325mg percocet and the pain subsides for about an hour. they put him on muscle relaxers which help a little. any advice would be great.
