yesterday afternoon I put on a new bodysuit, not even washed. minutes later I got rashes and hives everywhere. I immediately threw it in the laundry bin, took two benadryl and took a shower. later that day 80% of the hives we're gone. I got back from work today a little itchy and I checked in the mirror and I have hives again. I took 2 benadryl a hour ago and I just got out of the shower. should these hives go away soon? help!!
