Thanks Bluesfan. Yes you grasp it all so well as usual - there is probably not going to be any positive outcome for me from the oral surgeon's supportive consultation - especially because I have no jaw or mouth related symptoms presently beyond the small fibre ones. But somehow his support encouraged me not to give up my quest for answers or resign myself to the SFN necessarily being present and untreatable for the rest of my days. With time this boost in confidence diminishes but he did say he woukd write to my GP. I have to register with another GP practice in a month's time because we are relocating permanently soon so I may not be able to acces his letter easily though but we will see.
