I don't have a bump, and don't remember having one but it is almost 13 years old so pretty much just part of me. I do remember getting a "zit" around the hole about a month after I got it and I eventually got annoyed and popped it. I know...stupid, but it never came back lol! I was young. Hopefully it will heal with more time for you!
