|Kevin and Betsy,
I have been struggling with the same question.
I had a very slight poison ivy breakout that I was spraying with benadryl and covering with a bandaid. That helped the itch but the few bumps I had were not going away, so I started treating them with Calymine lotion and leaving them unwrapped and now I seem to have developed bigger red bumps, lots of them in the area where I had only had a few! I'm wondering if these are hive? Will this ever go away?
