Hi Dahlek and thank you for your welcome. I'll certainly go to the VMS thread to read up on nerve regeneration. I've read several recent and encouraging articles from a group in Utah about the positive affects of diet and exercise to promote intraepidermal nerve fiber growth in prediabetic patients.
My B12 is normal ~400. When I was at Johns Hopkins I had heard that values <400-500 could sometimes be considered low so I talked w/ my PCP about a B12 supplement. I was taking 1g/day for 3months - maybe much too short to be effective.
No spinal work done yet but SSA/SSB and antiHU antibodies were normal.
BTW - Dahlek is not the usual spelling from the old "Dr. Who" series is it. Remarkable what one can do with a little money for props and a set but a lot of imagination.
