Dog bite finger swelling up in pain two weeks after being bitten?

I was bitten by a small dog just over two weeks ago. It was just my right ring finger, no where on my hand or other fingers. Doctor did not prescribe antibiotics as the wounds (small puncture holes) were not deep. Saw him a few days later for checkup and wounds were healed over and swelling and pain gone from the finger. By the next week the wounds were gone and it was like I'd never been bitten.

But now almost two weeks after last doctor visit my finger has swelled back up and is severely painful, almost worst than before. I can't bend my finger either. I haven't broken my finger, it's not bruised, red, none of the bite wounds are red, no infection of any kind. It basically swelled up over night. I'm out of town and can't go see my doc.

What could be ailing my finger now? Pain meds are barely touching it, and I don't have a fever.
