Last night I noticed a rash on both arms. I took antihistamine and forgot about it. This morning it's got worse and has spread, so it's now on both arms and up around my neck and shoulders.
It's a bit itchy but not massively. I was at the gym yesterday and thought it could be something to do with my sweat glands but now I'm not so sure. Haven't changed detergent or soap or bath stuff. Do I need to go docs? I just can't really be arsed!
