I had 4 level ACDF w/inst. done on July 20th,'09. Post surg. pain seems to be getting worse as right shoulder and right arm cramping is gradually returning. I have been using spinalpac II bone stim. 24/7 to get fusion to take as quickly as possible. I have been told that adding valium helps with nerve endings that are effected from surgeory. Any advise would be helpful! I am hoping that after six week check-up and x-ray I can start physical therapy as that was my salvation after 3 level lumbar fusion done a little over two years ago.
