Ugh. This is becoming more and more common in our world. My neck is ravaged as well. I got an MRI last year after I lost feeling in my fingertips for several months straight. I was told that surgery was my best option, but because my situation was not as dire as yours it was not considered an absolute 'must.' I took many months off and have implemented a program of PT and traction, and have been able to return to the mats, though my style and and willingness to sit in chokes have obviously changed radically. But this is the part I think you may want to note: I had my first child 2 months ago, and the constant carrying of her, her gear, just the overall added and relentless workload have worn me down (like they do any new parents). And for the last two weeks specifically, my neck issues have followed the natural progression downstream and now my back is starting to spasm. So now I can't move my neck at full range of motion and I literally cannot pick up my daughter. THAT is fucking awful. AWFUL. I wish it upon no one. Now I obviously can't say for sure that it's all my neck's fault; like most long-time players I have injured just about everything over the course of my journey, but regardless of what caused it, the simple fact remains: YOU DO NOT WANT TO FUCK WITH YOUR NECK OR BACK. You're only 31; I don't know if you have a family yet or are planning to, but... don't you want to be able to be active with your kids? Or if kids aren't a part of the plan, you obviously want to be active for yourself.
I guess the point of all of this is just to say you should take what your doctors are saying very, VERY seriously. It is absolutely in the athlete's nature to not want to listen to any advice that signals the end of a playing career, and I think we have all been there looking for the alternative fix, the 'other' option. And maybe it exists for your situation and maybe it doesn't. But even if you get alternative advice, consider it very seriously against the advice of your medical professionals.
