2 years after rhinoplasty, painful bump on my nose. What could it be? Options? (photos)

I did the rhinoplasty 2 years ago. I don't remember when I felt the bump on my nose for the first time, but it was definitely more than a year ago. It's really tiny (On the right side of the middle) and not that visible, but it is really painful to touch it. When I told my doctor about my concerns, he suggested me to use lokoid + kelofibraze + lioton during ultrasound procedure. He also told me that "it is not a big deal" (however, he didn't conduct any tests/diagnostics). I did it myself by means of Zemits ultraglow led system, but afterall I felt more pain. What could it be?
