Tragus
The Tragus is a little prominent flap of skin and cartilage in front of the ear canal, this piercing is done by professional body piercers and should never be done by a piercing gun. To do so can lead to serious personal injury to the tissue and hearing.The tragus is the small external lobe of flesh of the ear closest to the skull. It is located in front of the concha. This lobe is conventionally pierced with a captive bead ring. The tragus has no nerve endings but some piercers experience pain.
An antitragus is a projection of the auricle of the ear extending to the tragus.
It's called a Tragus. The lip of the ear canal should be predominant and should move freely to cover the canal when pushed by the index finger. If the tragus is too small then healing and rejection could be problems. Only a professional body piercer can make that call by looking at your tragus. Do not pierce this with a piercing gun, there are a great deal of nerves and vessels in this area of the ear and a piercing stud can and will do serious damage that can not be repaired. Piercing guns are for ear lobes only.
most likely the tragus piercing. but that's still on the ear.
