Constant Random Itching & Hives This Week

I eat some tofu which is high in histamine and I suffer a major attack like never before. Then over the next few days, I accidentally keep eating other high histamine stuff like peanuts, fast food, soy sauce, and marinated meat. My face gets so much acne/hives, whereas rest of my body has none but itchiness still is all over and random. I've decided to finally take my allergist's advice from last year and buy some anti-histamine pills. But hey, at least a few months ago my body would stop overheating which forced me to stay up at night.
