Hi RSD-Angel,
I posted the other day that your rash is exactly the same as one I have had a couple of times. I was sent to a dermatologist and he diagnosed vasculitis. I am wondering what your doctor means when he calls it a "pain rash"
The good news is that if it is what I have had, it does go away eventually but may leave some very slighly darker skin where it was.

That leg/foot modelling career may not be over, just on hold.
