Alright, so a few weeks ago I slammed my thumb in the car door. Blood started to collect under my nail and of course I felt some pressure and it hurt a bit but I pulled through and everything was alright. But now it's at the time that my finger nail is supposed to fall off and all the blood from under my nail is gone (I'm guessing it leaked from a small cut near my cuticle) and I know it will fall off. The thing is, all this time I didn't go to a doctor (and I don't think I will get an appointment anytime soon) and have noticed a smell (it's not bad, but not very pleasant either). What should I do? It doesn't look infected.
