Starfish - I had a neck injury too. But unlike you, it did not affect me initially.
I was lucky. I walked away with some stiffness and went on to have kids, a job, etc.
The neck grew more painful and sx started cropping up a few years ago. One night I went to bed and suddenly both arms were in incredible pain, paralysed. That comes and goes, scary to think it may come and stay some day.
For a while, I lost the strength to play guitar, and that was a tough time for me. After some treatments, slowly I'm getting my jam back.
I played for 30 years, and now I pretty much have to relearn it. But that's okay as long as I can.
I think like you do - I could have been like Chris Reeves. But there must be some reason I'm not, so there's no time to freak out, no time to waste. I'll do what I can do as long as I can do it.
