Wow, Kim, I hope it is caused from the stress and it will go away when your stress moves out.

My husband had something that no doctor could diagnose too. It wasn't at all what you described, he had HUGE blisters all over his feet and legs. I remember how frustrating it was to hear doctor after doctor say "I've never seen anything like that". They never did diagnose it, but after a couple rounds of steroids it did go away.
