Since there is a clear history of trauma causing nose bleeding, first of all, you need to go to the hospital to check the nasal bone CT first to exclude whether there is a nasal bone fracture, if there is a nasal bone fracture, you need to apply local cold compress within 24 hours, and then apply local hot compress after more than 24 hours, and observe whether the nose is centered after 5 days. If the misalignment is obvious, nasal bone fracture revision can be performed, and antibiotics will be applied after surgery. If there is no nasal bone fracture, consider soft tissue injury in the nose and consider having mucosal vascular bleeding. If there is a large amount of bleeding, nasal filling can be performed. If there is only a small amount of bleeding, it does not need to be treated and is curable. It is also necessary to observe whether there are symptoms related to the eyes as well as the head, and if there are symptoms related to diplopia, loss of vision, protruding eyelids, etc., it is necessary to go to the hospital immediately.
