That is interesting. I wonder if it pays to repeat the skin biopsy?

In my calf area, I had 2 fibers per mm and transverse fibers. That result was from a biopsy done quite a while ago. Seems like mine are dead ducks. My calf area was worse than foot. I am so glad my neuro knew what he was doing because all EMGs were normal.

Would overbranching be an attempt of the body to regrow?

Also, would ALL small fiber neuropathy be found on a skin biopsy? I mean, if one has a negative biopsy, then SFN is not one's problem? I guess a more technical way to word that, is there such a thing as false negatives?
