2 months ago I had my cartilage pierced.I later got a like bump like thing on the inside of my ear were the piercing goes in and my friend took it off and it bled a bit and she cleaned it and put my ear ring back in.Now my I took my earring off to shower and I noticed it had puss coming out from whatever it was that she popped or took out .it doesn't hurt but it has me very worried.What can I do?what do you think it was?

Did you have it pierced by a piercer or with one of those guns?
Are you cleaning it with sea salt? Antibacterial soap?
Cartilage bumps can sometimes be dissolved by crushing up aspirin and rubbing on the bump. Just continue the sea salt rinses and DON'T touch your piercing unless you you are cleaning it.
Don't be taking your piercing out if you want to keep it. Taking it out and putting it back in creates unneeded trauma.
What type of metal is the jewelry?
