Unlike a cut, a puncture wound does not normally result in severe bleeding. Although excruciating, it may look harmless as the skin around the wound merely closes. But puncture wounds carry a possibility of infection and if left unattended can result in severe complications.
Puncture wounds from nails
Injuries caused by stepping on a nail that punctures through a shoe are particularly susceptible to infection. If the wound is due to stepping on a nail or a fragment of glass, consult a doctor who might recommend a tetanus injection or booster.
Animal bites
A bite from a domestic pet or another individual that results in a puncture wound should be considered and treated as a severe wound. If the bleeding is substantial or the item that caused the wound seems unhygienic, thoroughly clean the wounded area with mild anti-bacterial cleanser and water and seek expert medical help as soon as possible.
First aid steps
- If the injury is minor, clean it with soap and water and smear an antibiotic cream such as Neosporin to avoid infection.
- Dress the wound with an antiseptic bandage and swap the dressing regularly. Keep a close eye on the wound for a few days to avoid an onset of an infection from any fragments deep in the wound.
- If there is persistent inflammation or if the wound starts to secrete pus, see a doctor right away.
