Neurosurgeon says neck brace, Chiro says no.?

With that kind of damage physical therapy would be better than a chiropractor. Your your discs and nerves could become even more damaged with a crack the wrong way or too hard. Muscle stretching would be of more use. I have used a chiro on and off most of my life, but it is only a temporary fix, and it sounds like you need a long term solution. I would listen to the neurosurgeon. I have a similar appt. coming up and will be going to physical therapy. Good luck.
