I would hate to claim that just because I got away with it, anyone could.
I had a "severely" herniated C6/7 disk from an auto accident in '02 that was inpinging into the spinal canal at first. Six months later, a follow up MRI showed the disk had totally collapsed and the two vertebrae were fusing together (the fusion was noticed through a CT). Problem was, C-6 and 7 were actually stair-stepped and this in effect was kinking the spinal canal (I think reducing it by 7mm).
The surgeon described this situation as "dangerous". I scheduled surgery a few weeks later, however circumstances delayed the surgery till almost exactly a year from the auto accident. At first after getting the bad news I was being very careful, but during the time waiting I finally decided to continue walking and had to continue driving.
I swear, there were never any symptoms from spinal cord damage, nor are there any showing up to this day. Unfortunately, the nerve root to my left arm was damaged and all this waiting did not help the situation. So that is most likely perminent. But I am really glad that I'm not in a wheelchair to this day.
