I've been wearing earrings that were supposed to be for sensitive ears, but they made my ear have a green discharge type thing. The green stuff is also on the earrings. It's been like this for a few weeks, and today they were kind of sore and itchy, so I touched my earlobes and there was a crusty/hard covering on them. When I looked in the mirror, the crust type thing was white. Is this an allergic reaction to the earrings, or something entirely different?
