Sorry about that, Cat.
I had a chat with my neuro last Friday. I happened to mention that my feet had been bothering me. (My symptoms really don't sound like yours, though.)
He actually made a note of it so I asked him why. He said that means the lesion in my neck is healing. I really can't expound on this, but maybe someone else will.
My feet aren't excrutiating, but I've decided to give up pumps for awhile.
Good luck to you!
