Hi, please can you give me some advice? Often (for over a year), I get a rash on my neck and chest, which does not look like hives, it is not raised or spotty and it is just a patchy rash. It comes up when I am stressed, hot, or emotional. It seems to be where I got sunburnt last year, it faded, obviously. However when I get hot, emotional or stressed, it appears, it is really embarrassing because everyone thinks I ve been on a sun bed! I am taking anti allergy tablets for hayfever and they do nothing. Thank you.
