Chirag Global26 Jun, 2025Health

A pilonidal sinus is a narrow tract beneath the skin. It most commonly develops at the top of the buttocks, in the crease between the cheeks. If infected, it will become a painful abscess or cyst. The cyst will tend to trap hair, dirt, and dead skin. It will leak pus or blood and may have an odour.
