To be clear - I do have pain as well, just not severe most of the time. I believe the source of my pain is SFN, not something else now. It's always hard to describe exactly your symptoms to people I find. I don't find the words "tingling" or "pins and needles" really appropriate for what I feel, nonetheless I use them because that's what other people say and its sort of approximates what I feel. It is pain that stops me doing things a lot of the time. I also have a lot of urges to clench my toes in particular, if that is helpful.. I guess it is all standard neurological disturbance potentially with no solution.. 🙁
