The skin biopsy was done only above the ankles on each leg. I'm hoping the neurophysiologist will perhaps do some further tests.... and clearly explain the results of the EMG and skin biopsy for me. Thanks again! Mike

I think doing the biopsy on the thigh also (and in my case, the knee) answers the question of length-dependent small fiber neuropathy vs non-length dependent. I believe a podiatrist cannot work above the ankle. It was nice of him to do what he could though. My biopsies showed that I have length-dependent SFN, meaning it was only showing at the ankle two years ago, but will progress up from there.
