if you are a keloid former then any skin injury whether intentional or accidental has the potential for forming another keloid. this is the chance you will need to take if you decide to pierce your tragus. there is not way to predict if this new piercing will result in a new or even bigger keloid.
i have a keloid on my lobe. i've been thinking about getting my tragus pierced & wanted to know if that was a good idea? . my keloid is fairly small and do keloids on grow on parts of the ear that are meatier?
