Is the growth of a bump on bridge of nose after rhinoplasty normal?
It's very unusual for a bump to "grow" after rhinoplasty. What typically happens is that as the swelling does down the bump that was already there is revealed. As you suggested in your question, it can take up to 12 months to fully heal after rhinoplasty. You may see some improvement in this bump as you heal. Keep in close contact with your surgeon. If the bump persists you will likely require additional reduction of the bony part of your nasal bridge to improve your result. Best.
