Skin Abscesses
What are skin abscesses?
Skin abscesses are pockets of pus in your skin. Pus is a thick fluid your body makes when it fights infection. You can also have abscesses inside your body.

Skin abscesses are caused by a bacterial infection, usually due to Staphylococcus bacteria (staph infection)
-
Sometimes, you get the bacteria through a break in the skin or a hair follicle (where the hair grows out)

Abscesses are painful bumps full of pus

Doctors will cut the abscess open to drain the pus and sometimes also give you antibiotics
