hives?

OK so the other day out of nowhere i started getting itchy little patches around my mouth and chin area.

I am allergic to peanuts however did not ingest or come in to contact with any. I bought a cute little bonsai plant which i gave to my sister in case it caused to outbreak but its now the next morning and i still see hive marks from last night . what should i do in the mean time until my doctors appointment? is it safe to wear my usual makeup ? Also it still burns a lot. any advice or tips? thanks ladies 🌼🌹💓
