Update!
It's been a little over 40 hours.
Within the first four hours, swelling went past the knuckles.
Went to the doc. Got an antibiotic and a steroid shot, and I am now on Staph Infection meds.
As of now, cold compressions have helped the swelling, as well as flexing the fingers. My arm and hand is a bit sore from the skin stretching as well as stretching of tendons, etc. Otherwise, it's just mild numbness. Had a fever of 99.something yesterday, but it went away quickly.

Okay, just wondering... you let him latch on to you for 3 minutes just to see what would happen?

Do you have allergies to ant bites, centipede bites, bee stings, etc.? Then you might just want to go to the doctor and get that taken care of. If not, then just wait it out and see how you feel by tomorrow.
Snake bites never really bother me, so I(stupidly) took my sweet time trying to get him off, XD Usually, a whiff of beer or cold water makes my snakes let go, but Atticus went unfazed.
Oddly enough, I don't react badly to any insect bites or stings, so I dunno why this got so icky. XDD
