I actually noticed that the bottom of my feet are shiny a few days ago, but I think they've been like that for a while now, before my PN ever started. I should say, before my PN ever started to BOTHER me.

But I am in the process of figuring out of mine is diabetes related or not - my fasting and A1C are all at the very high end of "normal" and I've been testing my own sugars lately and there have been a few in the prediabetic and even diabetic range.

I am glad you posted this question, though, because I did some research and found a lot about shiny feet and hands being a sign of diabetes. The more evidence I have to bring to my first neuro appointment that my PN could be caused by high blood sugar, the better.
