hello dr mere baby ko birth time se hi back side me scaral dimple jaisa hai kya ye normal hai?

A. Most sacral dimples are harmless and don't need treatment. A sacral dimple can be a sign of a serious spinal problem in a newborn if the dimple is large or appears near a tuft of hair, skin tag, lump or discolored area. In these instances, your child's health care provider may recommend an imaging test.
