I have severe small fiber neuropathy finally confirmed through skin punch biopsy above my right ankle.

When this pain in my feet started I went to my PCP and she ran the 'regular' tests for neuropathy which are the tests u have had run.

When they were all normal I asked my foot and ankle Dr to do a skin biopsy which came back positive and severe. Thank goodness this only took me 4 months to get a DX.

Mine was from chemotherapy and being prediabetic during chemo.

Not sure this will help u but the more people comment the better I say. Lol
