Hi and welcome to Healingwell. The problem with allergic reactions is that they can occur at anytime regardless of a history. It's good that you are seeing a derm to see exactly what it is. Hopefully they will be able to help you. Sounds sort of like a heat rash honestly. Do you prespire alot? Do you play sports?
