Whenever I get hot, even just warm I get horrible horrible itching. A while back I had a doctors appointment and I asked about it. But they didn't really seem no know what it was. They just gave me a anti-histamine and that was it. It's been quite some time, and the anti-histamine seems to help a little, but the itchiness is still painfully intense plus the anti-histimine makes me too sleepy to do anything. Does anyone have any idea what is wrong with me? Is there something I can do to help make it stop? Please, any help is appreciated!
