The only thing i've eaten today is Taco Bell, a chilli cheese buriton with Mountain Dew. After i ate Taco Bell i went to the movies, and thats where i started to get itchy. it stared off with my head, i was so itchy that i thought i had head lice. but than my back and stomach got itchy. and i didn't see my body till i got home. i had red bumps all over my back and stomach and chest. so i showered. now its spread everywhere. even on my palms. what do i do??
