As one who had this surgery in 2001, I can say it helped tremendously! The pain and weakness in my arm was gone. And theybegan to question the MS diagnosis because the timeline of symptoms started with that pain with an auto accident a year prior to the MS diagnosis. I am told that whiplash can cause these cervical discs to rupture and press on nerves. I am also told that the banging around in the skull of the brain with such impact as an accident presents, can cause lesions or scarring in the brain which can mean nothing or can have residual effects.

So they may be related but MS does not cause discs to slip (at least I don't think it does).
