LOL. I figured someone would say that. It is highly possible.
It's just that the little itchy dot of a bite is so small compared with my knuckle. I didn't put two and two together.
I'm hoping. I do know it wasn't a snake.

Only have one bite mark.
Was bitten by some nasty spider in the floods back in January while I was out in the sludge in my back yard. My whole foot became swollen. I'd totally forgotten about that.
I'm hoping by tomorrow I'll feel better. If not it's off to the dreaded doctor. The aspirin helped tonight, but I don't like to take the stuff.
