Is it possible to remove a nose bump without breaking it?
Based on your one photo, you have a rather large nose bump and if you wish to have a straight nose, then it would require breaking the bones and re-positioning them. Yes, on occasion, a small bump can be shaved down -- but unfortunately, I doubt if that would be true in your case. The best answer for you would be to seek a consultation with a plastic surgeon for a hand's on exam and discussion.
