Skin Boil Picture

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 center 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. The picture below shows a boil that is in the processes of
releasing the puss that has built up in the process of fighting the
infection.
