How to treat a cartilage piercing infection?

umm, i really doubt that it is an infection, if it was, then the whole cartilage would be swollen, and the pus would be green. you probably have some scarring thing, i got it too when i hit my piercing really hard on something; what you have is similar to a keloid. the way to get rid of it is to keep with your sea salt soaks, and get some hyrdocortisone cream- apply that every morning and night for 15 minutes. also, a veeery common treatment for these is to change the earing to a smaller stud.
