Hi Teresa,
I have had the burn in hands and feet off and on for almost a year now. I don't have the problem with not being able to tell temperature though. Being a massage therapist not only am I on my feet all day but I am using my hands so some of it is occupational. Before my MS diagnosis they always said it was my fibromyalgia and gave me a steriod shot which does resove it for 3 months or so. Unfortunately it always comes back. I am sorry you are feeling so bad and really can't take anything for it. Hang in there. I hope you feel better.
Cindy
p.s Gretchen the shoes are the first to come off when I hit the door. Sometimes I wear flip flops to work because my feet are so bad.
