Hi I'm 12years old and a girl anyway one day I was itching on my stomach then I saw pimples all over my stomach that same day the next day more came and now I have these pimples on my inner thigh , back,legs ,armpits,arms and neck just everywhere the doc said it looks like chicken pox but it isn't so he gave me calamine lotion anti biotics and anti itching tablets what could it be?

If the doctor does not know after looking, how will will, perhaps allergic reaction, perhaps a irritation, if the doctor said chicken pox why do you think it is not ?
