I get what you are saying about nerve problems. My spine has compressed so much and there is enough arthritis in it that it has affected my sciatic nerve to the point where I can't walk any distance without my right foot getting completely numb. Couple this with a somewhat failed (my fault) meniscus surgery on the right knee makes me feel like a total cripple sometimes. I had a steroid injection in my spine a few days ago. My fingers are crossed that it will alleviate some of these problems.
I know I have written this many times before, but getting old is a huge bitch!
Best of recovery to you, you have at least got to an age most won't and are still going all be it with a few problems, I'm mid 40s with my issues, it worries me how I will be if i get to your age, wasn't a heavy juicer, but a heavy lifter. wouldn't change a thing but the shit took its toll thats for sure, no pain no gain, didn't realise the pain came 20 years later
