Can a Sacral Dimple Get Infected?

Some babies are born with a small dimple just above the crease of the buttocks, called a sacral dimple. Sacral dimples can become infected and form a pilonidal abscess.

When should I be concerned about a sacral dimple?

Most sacral dimples are harmless and don't require any treatment. Sacral dimples that are accompanied by a nearby tuft of hair, skin tag or certain types of skin discoloration are sometimes associated with a serious underlying abnormality of the spine or spinal cord.

Why does my sacral dimple hurt?

If it becomes infected, it can become swollen and cause pain. Sometimes pus and blood will ooze from the cyst. A sacral dimple is something you're born with and a pilonidal cyst is something that develops after birth. Anyone can develop a pilonidal cyst, but it's most common in young men.
