Since I've had ACDF it now seems I have a pinched nerve somewhere between my neck and down into my thumb. That's where it starts. Then it crawls across my hand until my wrist is actually painful. I can simply bend my head forward and make my thumb start zinging all the way up my arm. I had a nerve study done years ago on my ulnar nerve but try as I might I cannot for the life of me remember what they did. Can somebody please remind me what the procedure is like for a nerve study? I would really appreciate knowing before Friday what I'm in for. If anyone could enlighten me I'd be eternally grateful.
