Under normal circumstances, the wounds of tetanus are usually small and deep. There may be redness and swelling at the wound site. After a tetanus infection, when symptoms occur, the redness seen is different from the usual redness - it typically appears as a dark red. The wound might have a deep infection and produce pus, which is either white or blood-tinged. Additionally, there will be pain at the wound site, which feels severely painful to the touch, and sometimes the severe pain is felt even without touching it.
