Double Cartilage Piercing with bump!?

I have 18 piercings in my ears. I'm not sure of the correct terminology for those bumps, but the way I got rid of mine, popping them. It's painful, but worth if if you love your piercings. It will bleed, but not for long. Then just keep it clean. You also might want to find out if you could possibly be allergic to the metal.
