What Is a Pilonidal Sinus?
A pilonidal sinus, also known as jeep rider disease, is a small cavity or tract under the skin, usually near the tailbone (in the cleft between your buttocks). It is often caused when hair, sweat, and dirt get trapped under the skin, leading to infection and a tunnel or abscess formation. It mostly affects young adults and people who sit for long periods—like students, IT professionals, and drivers. It was also known as jeep rider disease.
