Could I be allergic to DC?

I was born and raised in the DMV and in DC proper for most of the last decade. For the first time ever, my face broke out in red itchy oozy spots in November.

I’ve never had any skin problems, so it was quite shocking. I’ve traveled out of the area twice since then, once for a week and once for two weeks. Both of those times, my face cleared up. Within 48 hours of being outside in DC, the exact same spots came back. I think it’s the outside specifically because I was home sick for a week upon my last return and my face was fine until I left the house.

I’ve been to the doctor and received a prescription ointment, and that didn’t work. I’ve tried basically all OTC options and nothing has worked.

Has this happened to anyone else? Anything else I should be trying?
