I got my ears pierced back in June or july. They both healed fine. I wore a dangle earring in my left ear one day, and my ear was red and irritated by the end of the day. I have not worn it since. (About 3 weeks ago). Now that ear has a hard lump near the piercing, about 4 mm away. My ear appears swollen from it, and it is tender, but only on one side of my lobe. It doesnt seem to be the piercing itself, but it does cause slight irritation in my lobe. What should I do?
