so i had my cartilage piercing 3 months ago by a gun. i took it out like 2 weeks ago and there was a bump on the back of the piercing. people told me that it doesnt go away!? is it true? but then i heard u can shrink it by soaking it in salty water? would that help? i dont think its a keliod because sometimes the bump will be small and sometimes it will be bigger. so yeah
