What is a Sacral Dimple?
A sacral dimple, also called a pilonidal dimple, is a small hole located at middle of the back just above the buttocks.
You could have sacral dimple if you notice an indentation in the skin on the lower back — usually just above the crease between the buttocks. Sacral dimples are small and shallow with fluid draining from the dimple; and/or swelling, redness or tenderness around the dimple.
When to See a Doctor
Some of the reasons to consult your doctor include: if you notice fluid draining from the dimple; if the dimple is very large or is accompanied by swelling, discoloration, drainage or tenderness. The dimple might be infected and form a cyst.
Your doctor may have you take one of the following tests: ultrasound, magnetic resonance imaging (MRI), physical examinations.
You can help heal sacral dimple by doing the following: keep the sacral dimples clean, dry and free of debris through good hygiene, including regular bathing. Remove hair regularly to prevent infection.
Preventatives and Precautions
A sacral dimple is a congenital condition, meaning it is present at birth. There are no known causes.

This sacral dimple problem is more likely to occur in people who: are obese, experienced trauma or irritation in the area, have excess body hair, sit for long periods of time, wear tight clothing, have hair growing into the skin in the crease between the buttocks.
