Sorry for not thinking of this sooner to share with all of you. My neurologist Dr. Charles Argoff from Albany Medical College, NY collaborated on a book with other Drs (some from Mayo Clinic) called
SMALL FIBERS, BIG PROBLEMS
A comprehensive patient guide to small fiber neuropathy. He mentioned it to me when I was first diagnosed with SFN this past February. It was written in 2017 due to the growing numbers of patients suffering from the disease.
After my fast and furious internet research had become confusing, I ordered the book from Amazon. It is such a simply stated tool in understanding SFN. I referred to it quite often in the early stages and it helped justify alot of what I was feeling. It helped me and I hope it can help you too!
