I had a cartilage piercing more than 2 years ago, and it never healed. It hurt a lot few days after the piercing, it got swollen, and every time I attempted to clean the wound, it felt like making another piercing putting the earring on. I never went back to check with my piercer, and eventually I took the earring off. Now I am left with a dark pimple that does not hurt, Can I redo the piercing? And how can I get rid of the pimple and the darkness?
