What is boil and purs

www.africapple.blogspot.com

A boil, is a localized infection deep in the skin. A
boil generally starts as a reddened, tender area.
Over time, the area becomes firm and hard.
Eventually, the centre of the abscess softens and
becomes filled with white cells that the body
sends to fight the infection. This collection of
white cells is known as pus. Finally, the pus
"forms a head" and drains out through the skin.
Skin abscesses may occur anywhere on the body.
They affect people of all ages.
