I appreciate it. I'm sure it's a spider bite though. It's got the two very distinct bite marks in the center of the red area that have scabbed over, with smallish white rings about both, and my room has been a hotbed for spiders recently as I see them very often. And there isn't any puss whatsoever, which my understanding was often more indicative of an infection.
The fang marks are pretty distinct in this case.
