I got this rush on and off for the last two years. Extremely itchy and hot. I seen dermatologists and I was told that may be a fix drug reaction but no one has seen it before, no allergy came up at the pat test. It lasts two weeks and goes only with antibiotics. prior the eruption(that is very sudden) I feel have flu symptoms.
Haw to add a picture? I will put it in my profile.
