I have a rash that started on the backs of my hands. at first I thought they were mosquito bites because they itch and look like them. However, a few days later there a whole bunch of them started to appear. Now I have them on the backs of my hands, the insides of my elbows, my forearms, buttocks, and underarms. I'm going to see a doctor about them but he can't see me for almost a week and these rashes are pretty irritating. what is it? any thoughts?
