The piercing of the tragus is not considered to be terribly painful because it does not have many nerve endings or blood flow. This type of piercing is considered to be quite susceptible to infection.
Hair often gets caught around the earring, and this is what increases the risk of infection. In extreme cases, tragus piercings have to be surgically removed. For this reason, the quality of the jewelry and tools used is extremely important.
Good aftercare is also pivotal. The tragus area must be cleaned gently with a disinfectant, and the piercing must not be handled with unwashed hands.
