I recommend that you go to your primary care doctor
to have your wound evaluated. It doesn't sound like a superficial wound from your description. Wounds are also concerning because if they are not properly cared for, it can lead to infection. Infections can spread deeper into the foot and surrounding tissues. Moreover, you may need a tetanus shot or tetanus booster shot if the wound is deep enough. The reason for the tetanus shot is to prevent the tetanus spores, if present on the prongs, to spread throughout your body. If there is surrounding redness at the wound site, it may be infected. You can use a pen to circle the red regions. If the areas are spreading, it could mean that you have cellulitis which is a superficial infection. If it is not treated, it can lead to necrotizing fasciitis, which is infection of the deeper tissues and may need surgical interventions. To be safe, I think you should go to your primary care doctor to have your wound evaluated. It can ease your worry
. Your doctor can take a look at it to determine if you need any antibiotics or tetanus shots. In the meantime, you should deep the wound dry and clean. You can put a dry bandage over it.
