So I have had my second lobe piercings done for about three months now and I changed them for the first time last night to silver earrings, though as I went to go clean them today I noticed a hard red pimple like thing behind one of them, this is a bad quality picture but it was the best I could get.

I cleaned it with some tea tree oil and Vitamin E... Help please?
