I drink a lot of Mountain Dew - usually 20 oz/day (once in a while 40 oz). Could my burning feet be related to that? The doctor is calling it unspecified neuropathy, because I do not have symptoms of diabetes and they don't know what's causing it. I've tried to correlate it to other things. It doesn't seem to be gluten, it doesn't seem to be my shoes, but it seems the more Mountain Dew I drink in a day the more my feet burn. I should add that there is no redness, swelling, or any other physical indication of reaction.
