What causes wounds, cuts and grazes?
2-minute read
Wounds can be caused by something sudden, such as a cut, a burn, a fall or a bad knock. People often have a wound after surgery.
Wounds can be caused by infections, such as infections after surgery and infections in insect bites.
Wounds can be caused by being immobile, such as bed sores or pressure injuries.
Wounds can also be caused by chronic illnesses. For example, people with diabetes can get infected wounds after a knock or scratch.
The signs of a wound are:
- a cut in the skin
- a graze to the skin
- redness and swelling around a mark
But you should see a doctor if:
- the wound is deep
- the wound is near your eye
- you notice changes around the wound, such as spreading redness, increased pain, tenderness or swelling
- the redness and swelling is increasing
- you develop a temperature
- the wound is from a bite, whether by an animal or another human
- the wound is contaminated with soil or saliva
- you have diabetes
- you’re not sure whether you’re up to date with your tetanus shots
