Is my belly button piercing infected (Picture Included)?

it looks completely normal to me. It might be because of irritation like if you have been messing with it or anything try to leave it alone and be sure not to get it stuck on anything. When you clean it try to make sure that you also get inside where the barbell is. If it has been more then 3 weeks and doesn't hurt i would advice you take it out and make sure that you clean where the barbell has been that way it gets completely clean. The bump near the top of the barbell near the ball is normal for a piercing, it will take it a while for the bump to go away but it will. If it does not clear up within a week or 2 send me an email
