Pus is a sign that a wound is infected but it is also a sign that your body is trying to fight the infection and heal the injury. Once an infection has started, your immune system begins trying to fight it off. It sends white blood cells to the area to destroy the bacteria.

What does pus oozing mean?

Pus is a substance that is produced by a battle between our immune cells and bacteria. “A wound that's oozing pus definitely means you have a bacterial infection,” said Dr. Brady Didion, a Marshfield Clinic family medicine physician. An incision or wound that's healing well looks slightly red and may seep clear fluid.

Should you squeeze pus out of a wound?

Do not squeeze the pus out of the abscess yourself, because this can easily spread the bacteria to other areas of your skin. If you use tissues to wipe any pus away from your abscess, dispose of them straight away to avoid germs spreading.
