Hard bumps on nose bridge and asymmetry after rhinoplasty - will I need a revision? (photos)

I had a rhinoplasty 7.5 months ago. I am developing three hard bumps which are visible when I flex my nose. Additionally, I have a lot of asymmetry pushing my nose to the left. It is much more asymmetrical and has noticeable bumps and irregularities in the bridge. I am concerned that I need a revision surgery and my surgeon does not seem concerned about any of this.
