I got my nose peirced when I was about 14.... many years ago, before computers.... just kidding I am only 33..... I also do not know what a keloid is... but I will tell you that I developed what looks like a tiny little mole or birthmark just below the peircing... it is not noticeable, but I have often worried that I may have done a stupid thing...... well... I did do a stupid thing, but you know what I mean... skin cancer or something. I still occasionally wear a tiny diamond in it... very occasionally... like once every year for a couple of days or something. For some reason it will itch, and wearing the stud is the only way to stop it... I dont know... I hope when you are my age your face doesnt fall off or something. If a "Keloid" can be removed... I would say go for it. whatever that is.
