Hello doctor, last night I was doing gym and I lifted dumbbell and when I was done with, I put it and in that very moment a metal rod was lying down and accidentally my middle finger skin got rubbed and I got a minor cut, and there was little very little blood! should I go out for tetanus shot last time I had tetanus shot in november! should I go out and take it or is it okay to stay low? And where I can get tetanus shot? In hospital?
