Hi and welcome to HCM.
It is recommended to have antitetanus shot after such injuries within 3 days.But you are probably vaccinated. Next time go to ER right after injury
. Now, you can treat it at home. Keep the wound clean and if you notice swelling,redness
or pusy discharge you should visit doctor because these are signs of inflammation. If there are no such signs it will heal in 5-7 days. Wish you good health.
