Rhinoplasty - Swollen bone right next to my nose. (photo)

I really hope someone can help! I had rhinoplasty done 4 years ago and wasn't happy with the results at all. However, that't not the issue. The issue is that I have had this bump on the right side, right next to my nose, since I had the surgery done. It feels like a bone and every now and then it starts swollowing up and I get swollen around the entire area and it hurts. It happens every 1-2 months. Can someone please tell me what the problem might be and whether I should get it checked?
