How to get rid of my nose bump?

Mette

I got my nose pierced March 3rd 2018. I took very good care of my piercing, (although I did get hit in the face with a ball when it was healing so I think that’s what it started from) and it doesn’t hurt, but it has this bump and I’ve tried several things to get rid of it and haven’t seen much results. What would you recommend, and when did you start seeing results?
