IF and only if,, the wound is deep with less bleeding than expected (wounds pucker up) then a tetanus shot would be good-a laceration that is bleeding well is self cleaning and requires butterfly bandage or stitches. I once had a head wound from a hanging gutter (this was after the 1972 flood of Corning NY) and when I went into the clinic, I told the staff to just stitch it up w/o any numbing shots. I saw a video of how lecerations were numbed up with too many pushes of the syringe on both sides of the wound.. 😣
