Thank you Debi, I believe mine was also via a skin biopsy, as the assistant informed me of this a few weeks after taking three plugs from my leg. I just viewed some info on mitochondrial disease and it looks like that can also trigger it. The horrible pain some experience with small fiber neuropathy seems to have been kind to me. I have had many episodes of severe pain, that are very difficult to describe, but they are so few, short and far between that I'd call it minor in nature. I hope you are as lucky as I in that regard.

Best regards,

Jeff
