If you want more direct info from personal experiences you are right where you need to be. As mentioned by @steeldove, read through posts on Connect. Important to remember that each experience can be unique but it always useful knowledge.

@rwinney Interesting that Dr. Glenn Lopate is listed as one of the authors of the book you found so helpful. I had an appointment last year with Dr. Lopate in St. Louis, Missouri, and found it a total waste of time and money. He most certainly is not terribly knowledgeable about SFN.

For those willing to wade through a medical article, here's one published in the latest edition of the Journal of the American Medical Association Neurology. https://neuropathycommons.org/sites/default/files/Oaklander_Nolano_SFN_2019.pdf It's a long article, but you may want to download it or print it to share with your doctor.
