I am the same age, 77 and suffering from many of the same issues. My worst problem is at L3-S1 but I do have nerve pain down my left leg and some numbness is my foot. I have been trying to decide whether or not to have surgery since last April. It is definitely not an easy decision. I had scheduled surgery for this month but had to postpone due to complications from a trigger finger release in August. I still can't decide whether or not to go through with the spine surgery. I need to take care of my hand first so that I can manage to use a walker after the spine surgery. I also have C-spine problems similar to yours. My neck is going to have to wait until I get my hand and my lumbar spine taken care of. None of this is easy and I understand your feelings. PM me if you want to talk.
