I have one of those in my ear piercing in pic 2 (at least I think so). I guess it's called Keloid. I'm pretty sure it is a keloid so I'm going to see a doctor tomorrow. I just can't figure out why I got it since I have treated my ear so well.
I have been doing body piercings for 14 years on others and probably 20 ish years on myself and as long as you keep them clean there is no reason why this should happen
