When I was having unexplained rashes for months, that is how I knew my antihistamines were wearing off, my palms would get incredibly red and itchy. It turns out that I probably had a reaction to a virus. If you are willing to try some antihistamines it might work.
I get the same reaction after a cold virus, my body is having an allergic reaction. Try antihistamines... they usually work within 20-30 mins. GL hun xx
