Degenerative disc disease (DDD)? How many?

So, it isn't JUST spinal stenosis that can compress the spinal nerve roots, this can do it too!

Anyway you look at it I know it’s painful.
Can spinal nerve roots die off from being compressed all the time?

Yes, I talked to my Chiropractor about this, the nerve in question for me from the central canal stenosis is the one that allows me to lift my leg to climb stairs! So if I lose this, I'm in big trouble! And that is just ONE!

I have arthritis in my neck. Is this similar? Can arthritis in the neck pinch nerves?
