@mitfit - My circumstances are about the same and I see @lecowing also says the same. The way yours has progressed is the same as mine. One foot, then the next, then numbness moves upward. In 2018, I was told that I have "a little in the hands" but that has not been too much of an issue other than picking up small things. I am fortunate not to have pain but that constant tight sock feeling, numbness with poor balance is an on going problem and you are unfortunately right, not much to stop it. As I've been told by some docs, try to treat the symptoms if you can, but don't chase down the cure.
