Hi there . Just thought I would let you know sisters results are back and is positive for sfn. Proff told me when we saw him back in October my results were not in keeping with a genetic neuropathy as showing increased nerve fibers. He has said my sisters is in keeping with an autoimmune immune disease. Her actual neurologist told her no point in getting biopsy as will be genetic. Was confusing. However proff commented that it was interesting we both have it. Any thoughts? ? Anyway merry Xmas 😀😀
