It is the most accurate test available for small fiber neuropathy.

It is a punch biopsy, which means it is about 3 millimeters in width, and it is a perfect round circle, that gets punched out of your skin-pretty far down, so it gets the whole thickness.

They numb the area, but it is a deep cut, do I still felt it a bit-but nothing crazy.

I kept it bandaged for a little over a week because it is deep. I still have a bit of a scar from my two biopsies, but the fade as time goes-the one on my ankle slower than the one on my thigh-but everything heals slower at the ankle due to its distance from the heart.

I had two locations done-upper thigh and ankle-both outer (distal). Not sure if it is common or not to have two biopsies taken at once. For me, I'm glad, as it showed my neuropathy was not length dependent, as I had damage in both the ankle and the thigh.
