Hey, recently (under a year) I've noticed that whenever I feel warm, or in an uncomfortable situation, my skin feels really itchy, sort of like a prickly heat, mainly over my chest and arms. Whenever i'd scratch to get rid of the itch, another part of my body would become itchy, and it goes on... It happens mostly in the shower, and i'd go to itch myself, and end up having red marks all over my body from where i've scratched, but also happens when im in bed trying to get to sleep, or even answering a question at school. If I cool myself down then the itchyness stops, but this problem is a worry to me, like if it prevents me from doing certain things, for example at a job interview, I dont really want to be sat there scratching the hell out of myself if im nervous. I'm only 16 years old and don't really do anything out of the ordinary... Thanks for the help, Danny.
