Hugs hun. Sorry it's not the news you wanted.

I know this seems really out there, but have you tried blackstrap molasses (orally) for the psoriasis. My DH's psoriasis is nowhere near that bad, but the molasses clears it up amazingly. There are lots of stories online about it.

Best thing is you can get it from the supermarket (often in the health food section, and must be blackstrap). Figure it's worth a try?

HTH xo
