Hi! I recently got my ear pierced, and I used hydrogen peroxide to clean it. But there was a black dot where the piercing was put from the marker used to show the specific spot, and I tried to scrub it off with hydrogen peroxide and rubbing alcohol. I let the peroxide sit for a bit and the dot did not go away. And now, about 2 days later, I have a greenish brown scab on the area and it's very dry. Did I burn the skin or is the ear infected?
