So sorry you have such pain. I’m no expert, but since you know there is long nerve damage and SFN, how would the biopsy show the cause? Also, as I recall you had some spine damage that caused it? Is that still thought to be the reason for it?

I don’t have any pain, and for that for that I am grateful, but I was under the impression that the only treatment for the pain from neuropathy are meds like Gabapentin. Do you have particular concerns about the biopsy?
