I hit my nose a week after septoplasty and I was wondering if I did any damage?

It is difficult to know for sure if damage was done but you are only 1 week out from surgery so it certainly is possible.  I recommend you contact your surgeon for evaluation.

Hi  bellaam2,If you have not done any other Rhinoplasty procedure aside from septoplasty, then hitting the nose should not have any impact on the septum unless the force was so strong it caused some bleeding.
