that diagnosis? What other reports indicate just that and maybe something not auto-immune?
I actually considered such an approach after I'd had a solid CIDP onset? But could find very little on the subject regarding small fibres....Larger nerves and nerve channels, yes, for but those little 'things' that go EVERYWHERE? Nothing. Too much too all over I guess.
I just did a quick web search and really didn't come up w/much for small nerve issues. And that was negative at best. Sigh.

If you could tell us a bit more about your PN, onset and what tests you've had, lots of others here could help you A LOT! Please try not to be too shy?
And ask questions! None are too silly....I've asked lots of them! Sometimes it's those 'little silly things' that count!
Please chime in soon and often! 's - j
