I had my upper-ear cartilage pierced 5-6 years ago and decided to get rid of it last summer. It kelioded slightly when I pierced it and it occasionally flaired up since then. Last summer I decided I was tired of it and haven't worn a hoop in it since. My problem is that it still occasionally bothers me. For instance, last night my upper ear started throbbing, and when I lightly touched it, puss popped out. I know that cartilage can never regrow, but I thought that it would be healed more than this after 7 months with no jewelry in. Is there anything I can do to help it heal permenantly?
