Rash all over body

I have a 21 year old son, who has been having an allergy which is like a heat bump rash all over his body - it comes up anytime he is stressed, or hot or at random times! It stings like (stinging nettles he says) and then after a few moments goes down. It is very annoying to him and happened so much recently, that he would like to know what to do.
Thank you, Joan

Re: Rash all over body

Dear Joan, thanks for your message and sorry to hear about your son. What you describe sounds very much like a physical urticaria - either exercise or heat induced urticaria or something called cholinergic urticaria. These would generally respond very well to high dose anti-histamine but I would suggest getting him seen by a Dermatologist to confirm the diagnosis and it’s worth taking some pictures of the outbreak along with you. Hope that helps.
