Hello John. Hope you are well. Is there any I formation on Mayo if podiatrist do small fiber neuropathy skin biopsy? I am thinking if I could rule out SFN, than maybe these burning symptoms on the bottom of my feet and on shins and calves just might be just from my back. Where are these biopsies usually done. From what I am reading, right above ankle, one by k ee, and one right below hip. I just wonder if any member on here has had a SFN Biopsy done by a Podiatrist? Thanks.
