Pilonidal Cyst Symptoms and Signs

As previously mentioned, some individuals with a pilonidal cyst may be asymptomatic, and the only finding may be a dimple or an opening in the skin (sinus tract) in the sacrococcygeal area. However, if the pilonidal cyst becomes infected, the following signs and symptoms may develop:

• pain over the lower spine,



• redness of the skin,



• warmth of the skin,



• localized swelling over the lower spine,



• drainage of pus from an opening in the skin (sinus tract) over the lower spine, or



• fever (uncommon).

Rarely, pilonidal cysts can develop in other areas of the body such as the hands.
