Over the last half hour (that fast) I have developed a really weird, itchy rash pretty much all over my chest (which is a lot of surface area :dry. I took an antihistamine but it's still spreading, even though I'm not scratching it. I have never had a rash like this before, I get eczema when I am stressed (and I am definitely stressed) but this is not eczema. Help! :unsure: Am about to phone NHS Direct but what a waste of time that will be. It will take me 8 hours to explain what the rash even looks like. I dislike talking about things like this on NHS Direct. Anyone have any bright ideas?
