Okay, so I’m not quite sure what I have–it’s just that when I get hot for any reason, I start getting itching all over my body. The itching is really bad, and I also get some minor itch on my scalp.
The itching is like a needle itch–a little prickly. But like others here I don’t get this while taking hot showers, just when my body temperature rises. Also the photos I have seen my heat hives are not like that, the photos looks way more intense.
I just get really light red patches which doesn’t last long. Do I have cholinergic urticaria?
