Can sacral or pilonidal dimples be harmful? the surrounding are is beginning to itch for me and i'm just wondering what my options are for getting rid

Abscess: Pilonidal and sacral dimples can develop into abscesses and these can be problematic. The best options are to get a formal excision done by a surgeon. I would recommend an evaluation with your doctor to make sure this is not infected.

Recommendation : Effective way to resolve this problem is surgical removal of pilonidal cyst. Please see a doctor as soon as possible, if it itches
