I got a rhinoplasty a year ago and 2 mo. ago and currently have a small but noticeable bump on my bridge due to scar tissue. I have gotten one steroid shot when I was 8-9 mo. post op but it is still there. The doctor suggested shaving down the fibrosis. Will shaving down fix my issue? How is this done?will it grow back? what is post care like and common complications?
