Is a post op Rhinoplasty hump normal? (photo)

Don't worry.  At three weeks it is not unusual to have swelling on the bridge of your nose that can look like a hump.  I am sure your surgeon told you that swelling can last almost a year with a rhinoplasty, so try to not evaluate your nose every day so early.  It will change day to day and with exercise, stress, heat, and time of day.  Discuss with your surgoen your concerns but try to remember the conversation you had with him/her before surgery.  Good luck.
