What Is a Septum Piercing?
A septum piercing is a piercing of the so called nasal septum – nasal septum separates the left and right nostrils. The procedure can be quite painful and is sometimes considered as one of the most painful piercings. The procedure includes the needle going through the thin piece of flesh towards the front of a person’s nose This is called the columella, but is often referred to as the “sweet spot”. It is interesting that in fact some people do not have a columella, but the piercing can be done through the cartilage.
