The bump you're seeing on your nose could be related to swelling or there could be residual bone or cartilage if part of your rhinoplasty involved removing or reducing a bump. In any case, it would be wisest to wait and follow up with your physician for a few months before making any judgments regarding your nose.
Two weeks is still too early to know what the end result will look like. I tell my patients that we cannot really make any assessments until about 6 months after surgery. I know its hard, but be patient. Best of luck.
Considering you are only 2 weeks out from a rhinoplasty, having little bumps along the bridge is normal. It is typically due to the swelling. With time it should go down assuming that there is not any cartilage/bone under the skin. Be patient and continue to follow-up with your surgeon.
Yes, sometimes these bumps are a result of a little swelling or surgical debris. Be patient, give it time, and consult your surgeon.
