Man, go get it treated by a doctor. Why take an unnecessary chance with your health? You may have a piece of the RTC's spine trapped in the wound. I believe in pinching pennies and all, but some things are definitely worth the money spent. I hope that you are ok, no matter what you decide to do.
That's gross, go get it checked. I had a stab from a small pim cat that penetrated deeply. Ignored it for a couple days until it started swelling up my hand. Had to take Keflex to fix the infection.
