16 months post rhinoplasty. Is it possible that I am still healing and experiencing prolonged swelling?

Hello! I had a primary rhinoplasty almost 16 months ago, and I thought all swelling would go away by now. But when I wear sunglasses, I get a visible trace (some depth and redness) on the right side of the nose, and nothing on the left side. Is it possible that there is still some swelling left/the nose is still healing? Thank you very much!
