I got my cartilage peirced about 7 months ago and I still have trouble with it sometimes. Every once in a while it gets really sore and gets a swollen bump on the back. I don't know if I should or not but I poke the bump with a clean needle and it oozes puss first and then bright red blood. I clean the spot really well then and let it heal and it is just fine for a few weeks and then it happens again. (it has only been doing this recently, not the whole 7 months) I had it done in a clean licensed peircing place and they used a sterling sliver hoop. What is going on? Is my ear rejecting the peircing? I am planing on getting another peircing in the other ear soon. Should I wait until this peircing figures out what it is doing?
