Okay, so i got my cartilage pierced about 8 ish months ago, on the second month, a bump appeared. mind you, this was my first piercing. i have a hoop in and i wouldn't move and play with it. it became infected, i got rid of the infection, it no longer hurts but there is still a bump on the back and front. it's not as big anymore but i've tried everything, the only thing that actually started working was aspirin, sea salt, tea tree oil and water all mixed in to make a paste. i've still been using this method and it's slowly working.
