You have my complete sypmtahy! I have been in your situation, and it is pure, pure agony! I've decided one of the punishments of hell is (or well, could be) extreme, inescapable itching. Do you have (or have access to) any menthol cream? That gives a cool feeling to the skin and helps with the itching. Of course, when it's all over your body, you need more than a little tube. My dr. prescribed it for me (called "Sarna Lotion" I think) when I had a head-to-toe itchy rash from an allergic reaction to a medication. I'm praying for you!
