I did read that whole site... and I found a lot of very good information, but not about large fiber PN. Maybe I am just stupid. I don't know. I am new to all of this and I am not medical minded. I don't understand medical terms and that's why I am asking for a website that explains it in simple, everyday terms. I just want to know in everyday language what the differences are in the symptoms between the two (large and small fiber). If I have all the symptoms of small fiber, why does my neurologist tell me I have large fiber PN? I can't find any websites that explain large fiber PN and what symptoms come with it (that I can understand). I did order a book off of Amazon, but it hasn't arrived yet.
