Two supplements I've used and posted about here are:

Inosine and Sphingolin and I've been off them for a while but have them on order to go on for a while again. You can do a search on them and give one or both a 3 month trial at least.

If it burns and tingles, it's neuropathy, don't need a doc for this dx. I've never talked to a doc about it as I've read enough here and now what I am dealing with. Gluten is a good thing to get rid of period.
