I got my ear pierced ( cartilage) last march 14. It was actually a gun-pierced. On the first two days, it was still OK but on the third day, it began to swell. I'm also encountering redness and I' ve seen some yellowish discharge on it. My classmate told me that its not just reddish. Its like purplish in color. I don't know what to do. Can you help me heal it. Thank you.
