A Pilonidal cyst is a sac-like growth near the tailbone filled with hair and skin debris. Pilonidal cysts typically develop due to hair penetrating the skin and becoming trapped. If infected, it can cause severe pain.
Treatment is required for pilonidal cysts that cause pain. These cysts can be one-time cysts or recurrent. If left untreated, chronic pilonidal cyst can lead to abscesses and sinus cavities.
Symptoms of a pilonidal cyst may not be present. However, if the cyst becomes infected, the surrounding skin may swell and cause pain. The following are signs of an infected pilonidal cyst:
