Puncture wounds are injuries caused by a sharp object penetrating the skin, creating a small hole. Common examples include injuries from nails, needles, or animal bites. These wounds can vary in depth and may damage underlying tissues, making them potentially serious. Due to their small size, puncture wounds can be difficult to clean properly, increasing the risk of infection. It's important to seek medical attention if a puncture wound is deep, shows signs of infection, or is caused by a rusty nail or animal bite, as these situations may require specific treatments or vaccinations.
