Well, nose surgery is not easy to suture, so you need your own platelets to stop the bleeding. During this period, blood will flow to your mouth. I suggest you spit it out immediately if there is blood in your mouth. If the blood is swallowed into your stomach, it will cause vomiting if it accumulates too much. At this time, the blood spit out is actually the blood in your nose.

The fever indicates that your wound has not healed. You can observe it again. If it has not subsided, consider whether it has caused infection.

numbness of lips is probably related to your breathing through your mouth.

generally speaking, there is nothing serious, please rest assured.

I wish you a speedy recovery!
