PILONIDAL DISEASE

What is pilonidal disease?

Pilonidal disease is a chronic or ongoing skin infection in the crease between the buttocks near the tailbone. It occurs when hair grows under the skin.


Pilonidal disease is more common in men, usually between the teenage years and 40 years of age. It is more common in people who are overweight or have thick, stiff body hair.

What are the symptoms?

Symptoms might range from a small tender dimple to a large painful area. Sitting may be painful. There may be fluid that drains from the area that is clear, cloudy, or bloody. The area may become infected and form an abscess. Symptoms of an abscess may include:

  • pus that oozes from the area
  • redness
  • tenderness and
  • sometimes fever, weakness, or nausea

How is it treated?

A healthcare provider will usually drain the abscess. After an abscess has been drained, it is very important to keep the area clean. The area should be shaved or a hair removal agent applied every 2 to 3 weeks. This will keep the hairs from growing under the skin again.


After an abscess has been drained, a space under the skin may form. This space is called a pilonidal sinus. The sinus connects to the skin with one or more small openings. Sometimes the sinus may get better by itself. Most of the time it has to be removed. A few people may even have several more infections in this area. These infections can cause swelling, pain, and have fluid draining from them. When an infection occurs, it almost always needs surgery.


When the pilonidal sinus has to be removed, it is usually done as an outpatient procedure. The sinus area may be stitched shut after the sinus is removed. Sometimes it may be left open to drain, and heal from the inside out. Another type of surgical procedure is closed with flaps. Your healthcare provider will discuss the options and help to select the best procedure for your situation.
