Hi there, I was bitten by my eight week old kitten three years ago on my index finger. Two weeks later I had a purple,black,green infected finger and swelling that extend up my arm, I lost my finger nail which has never grown back properly and suffer extremely painful stiffness in the first joint. It ended with surgery to open up finger to drain off pus ...not nice at all!
Please go to your doctors and cover yourself with antibiotics asap, yep it might be a bit extreme but better to be safe than sorry
