For swelling caused by trauma to the nose, local cold compresses need to be applied first 24 hours after the trauma, and then local hot compresses after more than 24 hours, which can accelerate blood circulation and reduce swelling faster. At the same time, it is necessary to check the CT of nasal bone at the hospital to exclude whether there is nasal bone fracture, and if there is nasal bone fracture, it is necessary to see whether there is nasal collapse, deviation, nasal bleeding and nasal congestion. If both of these symptoms are present, revision of the nasal bone fracture needs to be performed with a deadline of one week. If there is a nasal bone fracture without any symptoms, surgery is not necessary. You can take oral anti-inflammatory drugs to prevent infection, such as cefixime or roxithromycin, which will heal in about a week. During the treatment period, try to be less active, rest more, drink more water and avoid colds.
