Hi, @grammypj. You've asked all excellent questions. Over the years, I'veasked myself: Is this just aging, or is it PN? My neurologists (and oddly enough, I've got two) both assure me it's PN, or at least PN predominantly. I've chatted with a number of PN'ers who have large-fiber PN, like me, and who are not plagued with numbness and burning. Our odd balance seems the result of dead or dying nerves, in my case, a condition confirmed by both neurologists. They, too, tell me that the degree of sensation lost is still minimal, but not to be too discouraged if it grows progressively worse. In the meantime, I'll keep moving about – cautiously, when I must – and doing my daily PT.

I wish you a world of success in dealing with your PN!

Cheers!
