Rash All Over Upper Body Whenever I Get Sick...

Hi! Since I was in my teens every time I've gotten sick with any type of illness (generally common colds), I've gotten a bright, red rash all over my upper body and sometimes anywhere else warm (insides of elbows, groin, backs of knees). Initially, I thought it was probably a reaction to some medicine I was taking and dismissed it. At one point during college though, I got so fed up with this hideous rash that I decided not to take any medicine and live with the cold/flu symptoms. When the rash occurred without any medication, I went to a doctor for it. He said that in 26 years of medicine he had never seen anything like it and basically dismissed me as lying to him.

Since it does not itch (it does get stiff and puffy) and is mainly cosmetically irritating, I haven't worried too much about it. Just a few days ago, I got food poisoning, and the rash came along. I can't find any information on this anywhere, and I can't seem to find anyone else who shares this problem. Any ideas on why I get this rash every single time I get sick? It generally is at its worst when I am getting better.

  • Happens to me too. A couple hours after an intense fever red spots will appear on my chest and upper arms. These spots are slightly elevated and as more appear they start to coalesce (the upper chest is just one big red blob). It slowly fades away in 2 or 3 days after the fever went away. They are slightly itchy.

    Researching online the most similar thing I found was something called heat rash: https://www.medicinenet.com/heat_rash/article.htm

    Good to know I'm not the only one. I hope someone can tell us what is really going on...

  • I have this rash at the moment. I get it every time I feel unwell. Yesterday I felt I'll and had a sore throat. I came out in the rash on my stomach. Today I felt better but the rash spread to my chest back and lower arms. It feels a bit prickly. I used to think it was my hot water bottle. I couldn't get warm yesterday but I don't put the bottle by my back. I'm glad I am not the only one who gets this.

  • Hi everyone. I have the same problem. I'm 52 and for at least the last 5 years (maybe more), I get a rash every time I get a bad cold. Sometimes it starts as blotches, but the most recent one was more like a sunburn, but it doesn't hurt. Mostly on my arms and legs, but never my face or neck. I spoke to my doctor and its called viral exanthem. It's an autoimmune response to viruses.
    Mine go away when I get better. Nothing to worry about in most cases.
