Help - band aid allergic reaction

I had surgery Dec 10th. (3 weeks post op)

I have been wearing bandaids for about a week now over my nipples. I started getting itchy ASF but thought it was just my armpits swelling. I kept taking ibuprofen and benedryl. Then it got rly bad and I notice I have physical bumps around the edges of where the band aid was. I was bad and tried popping the bump on the second picture and it just bled and had skin come off super easy. I'm in a blizzard so I can't go out and get shit, I have neosporin and band aids though. I have gauze but nothing to hold it down.

Is it safe to have my nipples uncovered? And do I just take more benadryl? My nipples had shit shed off of them and they don't seem to be peeling amymore.

I'd ask my surgeons office but their responding hours aren't until morning.
