I have become allergic to some component of the dust in my environment, and when it directly contacts my skin, I get an almost instantaneous rash that gets worse the longer I ignore the itch and wait to remove the hoodie/shirt/socks/whatever (or stop petting the dog) that collected dust that then touched my skin.

like, actual huge visible welts, and they Itch like fire omfg, but they go away in 15-20

I thought it was something from the chickens or guineas, but then I reshuffled some ancient stored stuff in the basement that hasn't been touched since long before they arrived, and it broke me out so fucking bad! It looked like someone had been whipping my forearms, it was nuts.

I have never seen anything visible on my skin or on my clothes to show what is causing it. If I am obsessive about cleaning my dog and my floors and not letting anything sit out before it goes on me and not letting anything I'm going to wear to bed touch any other furniture, then it's fine, but that's exhausting

idk what the point of this is. Have you suddenly become allergic to anything? What was it and how is that going for you?
