i'm curious-what is a geographic tongue? Can you see maps on it? lol. Seriously though, curious what that is. Also it sounds like you should get tested for sure. Or eliminate gluten for a month to see how you feel?
Alot of makeup has gluten in it. Could be making it worse. Most topical things I've tried help with the itch, but only briefly and they don't help the rash go away at all.
Dang...you should try to find a dermatologist that can get you in today. That's a pretty bad flare up. It looks like mine have in the past. I have an appt this afternoon with a derm.
