I have a white looking bump on the inside of my nose that slightly covers the end bulb thing of the stud I have in. It hurts when I flare my nose, and there's a bump on the outside as well. It's where the piercing is. I'm not sure what's wrong nor what to do..

I've had the piercing for about 4-5 months now. I believe the bump just form today because I didn't see it yesterday..

Its nothing to worry about. Just use any piercing cleaner and it should go away. It happened with my cartilage piercings when I took them out to change them.
