Navel piercing (also referre to as belly button piercing) is a type of body piercing. It may heal quickly and with few problems, like an ear piercing, or may heal more like a surface piercing with the associated rejection risks and extended healing time. Healing of this piercing can also be complicated by irritation and damage caused by clothing, especially waistlines or tight clothing, or the position of the navel relative to the bend of the waist.
