Chatting with the girl I like, she suddenly said in sign language, I feel my nose is bleeding. What does that mean?

There are many reasons for nosebleeds, but about half of them can't be found. The tiny blood vessels in nasal mucosa are densely distributed, sensitive and fragile, and easy to rupture and bleed. Nosebleeds are common in preschool children. When nosebleeds, most people are used to holding their noses up, thinking that this can effectively stop bleeding, but it is actually wrong. It's just out of sight, but in fact the blood continues to flow-inward. The "backward posture" when nosebleeds has the following disadvantages: 1. It will make the blood that has flowed out of the nasal cavity flow back to the throat due to posture and gravity, and it has no real hemostatic effect. 2. Blood in the throat will be swallowed into the esophagus and gastrointestinal tract, which will stimulate the gastrointestinal mucosa to feel uncomfortable or vomit. 3. When the amount of bleeding is large, it is easy to inhale into the trachea and lungs, blocking the respiratory airflow and causing danger. The correct way is to keep the head in a normal upright or slightly forward posture, so that the blood that has flowed out can be discharged out of the nostrils, so as not to stay in the nasal cavity and interfere with the airflow of breathing.

What that girl said has nothing to do with you. Or did the boy she likes express his romantic feelings or something?
