Dude, I pretty much stopped breathing; "nasty allergic reaction" is the understatement of the century.
I'm seriously thinking about heading to the doctor; I really don't want to rack up another medical bill, though. At the same time, the bite area isn't swelling; I just have this red spot where I got bit. There's a dark center area that looks like a fang mark, but it is really hard to tell. A tiny wolf spider, maybe?
