For years now I have had this off and on problem, but when it comes it is unbearable. Just as I begin to sweat I begin to itch uncontrollably on my chest, back, and head. I do not get a rash or bumps and if I can cool off really fast or bear it until I'm in an all out sweat it instantly stops.
The thing is that it usually happens in the spring and fall, just as the weather is starting to change. I've looked into just about everything I can and if another Dr. tells me it is hives or my detergent I'm going to start running in place until I start to sweat and let them see how crazy it drives me. I was driving today and it hit me and I almost ran off of the road. I was literally getting undressed as I was driving with the AC on blast trying to cool off.
I've taken vacations to warmer climates and after a day or so the problem is gone but as soon as I get back and that transition between climates happens it's back. If I'm in the cool climate long enough it stops or if I'm in the warm climate it stops. It is just that in between time.
I've looked into *****ly Heat, Urticaria, Anemia, Detergents, Soaps. I've seen tons of other boards where lots of people are dealing with the same issue and even showed it to my Dr. but none of those boards had answers.
