Probably not: a problem. If you were bleeding profusely or had a deformity of your nose I might be worried but a little blood is no problem. If you are concerned call your ENT in the morning.

Probably not: If your nose looks symmetric then you are probably ok. If you are worried see your surgeon.

Rhinoplasty trauma: If you are concerned, have your surgeon evaluate your nose.
