My third post today... promise it won't be a habit! I have been acquainting myself with the many threads. What a wonderfully informative and supportive site.

I wanted to add that while my skin biopsy was "normal" for nerve fiber density (7.2 fibers/mm for distal thigh and 8.7 fibers/mm for distal leg) it did note morphologic occasional small axonal swellings. The neuro said they were of "uncertain clinical significance." Don't know if anyone here could elaborate on that or if it adds anything to my introductory posting.
Thank you to all that contribute to helping us newbees try to understand
