Hello. I suffer from a heat rash that appears over my parts of my body like my neck, chest and if really bad my shoulders and arms when I am nervous, happy, worrying, angry etc etc. I only started getting it about 2 years ago. So basically quite a lot. It's just red and blotchy, not bumpy atall. I always feel very warm when this happens and it's really affecting me in my daily life. I'm not an unsociable person, I have lots of friends, go out and do things all the time but yet this happens me in any type of situation. It happens my mummy sometimes too for no reason but not to any extent of mine. I'm wondering is there anything I can take that will help me with this problem??
