Abscess Treatment

Often, a skin abscess will not heal on its own without further intervention by your health-care provider. Initially, an abscess may feel firm and hardened (indurated), at which time incision and drainage may not be possible. However, once the abscess begins to "come to a head" and it becomes more soft and fluctuant, lancing it to evacuate the pus and relieve the pressure is the best course of action. Your health-care provider will open and drain the abscess (incision and drainage) using the following technique.

Skin Abscess Overview

A skin abscess is a localized collection of pus that generally develops in response to infection or to the presence of other foreign materials under the skin. An abscess is typically painful, and it appears as a swollen area that is warm to the touch. The skin surrounding an abscess typically appears pink or red.

Abscesses can develop in many parts of the body, but they usually involve the skin surface. Skin abscesses are often referred to as boils. Common sites affected include the armpits, groin, rectal area (perirectal abscess), the external vaginal area (Bartholin's abscess), and along the tailbone (pilonidal abscess). Inflammation surrounding hair follicles or sweat glands can lead to the formation of abscesses, as well. Abscesses can also affect the brain, kidneys, liver (hepatic abscess), lungs, breast, neck, teeth (dental abscess), and tonsils (peritonsillar abscess).

Unlike other infections, antibiotics alone will not typically cure a skin abscess. In general, abscesses must open and drain to improve. Although sometimes an abscess will open and drain spontaneously, it often needs to be lanced (incision and drainage) by a health-care provider. Certain abscesses may require drainage in an operating room.

Peritonsillar Abscess Overview

A peritonsillar abscess forms in the tissues of the throat next to one of the tonsils. An abscess is a collection of pus that forms near an area of infected skin or other soft tissue.

The abscess can cause pain, swelling, and, if severe, blockage of the throat. If the throat is blocked, swallowing, speaking, and even breathing become difficult.

  • When an infection of the tonsils (known as tonsillitis) spreads and causes infection in the soft tissues, a peritonsillar abscess may result.
  • Peritonsillar abscess is relatively common in adults but rare in infants and young children.

Peritonsillar Abscess Causes

A peritonsillar abscess is most often a complication of tonsillitis. The bacteria involved are similar to those that cause strep throat.

Streptococcal bacteria most commonly cause an infection in the soft tissue around the tonsils (usually just on one side)...
