A Boils is a red, swollen, painful bump under the skin that is caused
by an infection. Boils often start in an infected hair follicle. Bacteria
form an abscess or pocket of pus. Eventually, the pus may come to a head and
drain out through the skin. Boils can occur anywhere, but common sites
include the face, neck, armpits, buttocks, groin, and thighs.
There are several types of boils:
Furuncle or carbuncle – an abscess caused by the bacteria Staphylococcus aureus. This type sometimes occurs as several boils in a group.
Pilonidal cyst – an abscess that occurs in the crease of the buttocks. These almost always require medical treatment.
Cystic acne – an abscess that occurs when oil ducts become clogged and infected. This is more common in the teenage years.
Hidradenitis suppurativa – an uncommon disorder where multiple abscesses occur in the armpit and groin area.
