Are you taking alot of niacin? If not then ignore this but some people flush out when taking certain forms of this vitamin.

I too have terrible skin, oily, peeling, acne and it never clears up. I do not turn red but I do beleive the skin in general is a side effect of mercury interferring with adrenal function and thryoid function. Yeast is a biggy as mentioned already.
My cold hands/ feet thing went away with amalgam removal.
Definitely something "allergic" going on, I use this term loosely because allergies really are intolerances to things from an over stressed immune system, which is overstressed in our case from mercury assault.
