I have long used the almost scalding hot water trick for itchy over reactions. I also treat ant and mosquito bites this way to get relief; right before I go to bed and in the middle of the night if it is bad enough to wake me up.
I read somewhere that it has to do with long and short nerve fibers. The hot water overloads one of them, and blocks the signal of the other, if I recall correctly.
