baitcon | bites that just won't quit

Does anyone else have mysterious bug bites received at Baitcon that still haven't gone away?

I haven't been scratching them, and most of them have gone away but a few are still around, and one in particular took a turn for the worse today.

I *was* using hydrocortisone or lanacaine or after bite on it (depending on what was handy) and taking benadryl at night, but last night I didn't take any benadryl, and today I discovered that it had grown even larger than before! Not cool.

I can only assume that this one isn't a mosquito bite, since I've never had a mosquito bite that looked or behaved like this. :( What else was biting this summer at Baitcon?
