Symptoms

Pilonidal disease is often first recognized as a small dimple (called a "pit" or "sinus") at the top of or next to the crease of the buttocks. Hair may protrude from the pit, and several pits may be seen. Pilonidal disease often has no symptoms; however, when infection in the cyst flares up, you may have:

• Discomfort, redness, or swelling at the top of or next to the crease of the buttocks. The cyst can be so uncomfortable that sitting or walking is difficult.
• Cloudy fluid or blood draining from the pits.
• Fever over 100.5°F (38.1°C). However, fever is not common.

Although pilonidal disease occurs more in males, it does develop in females. Because of its location, a pilonidal cyst can also cause embarrassment and hinder social interaction. The location of the cyst should not keep you from seeking treatment, however, since help is available.

Because of similar symptoms, a pilonidal cyst is sometimes confused with Crohn's disease or a fistula or abscess next to the rectum.
