Hi @icelander19, Curiosity and learning are a good thing. I have idiopathic small fiber peripheral neuropathy which my neurologist thinks might be hereditary based on family history. Matthew B. Jensen who is a neurologist in Madison, Wisconsin has a YouTube channel with a lot great videos on the types and causes of neuropathy that you might find helpful for learning more - https://www.youtube.com/c/MatthewBJensen.
