What are the symptoms of a pilonidal sinus?
- Persistent pain in the tailbone area accompanied by an abscess within the crease of the buttock. If the abscess ruptures, drainage or pus may also be present.
- Chronic infection may develop if the infection has spread beyond the site of the sinus and is poorly drained.
- Symptoms of chronic infection include bloodstains or cloudy drainage on your child's underclothes.
