I have these red bumps that apear on my chest, stomach and shoulders that start out red some clear liquid inside most that heal over time but they leave a dark spot kind of bumpy not flush or smooth with rest of skin, I've had my dermatologist look at it but he said its something I caught in the air and there's not much i can do about it, I would like to at least know what it is, and hopefully figure out how to stop it, for now I'm just putting hydrocortisone cream as he directed. Please help if you can.
