After an impact to the nose, intervention can be made by applying cold compresses first, hot compresses after 48 hours, or in the case of a fracture, surgery may be required. Cold compresses can be applied to the nose for a short period of time to constrict local blood vessels, stop local bleeding and reduce swelling. After applying cold compresses, it is recommended to go to the hospital in time and have a CT examination to determine whether there is any serious injury such as nasal bone fracture or orbital bone fracture, and if there is such an injury, surgery may be needed to repair it. If it is only local bruising and swelling, after 48 hours of applying ice, local hot compresses can be applied to promote local blood circulation and the absorption and dissipation of the bruises. At the same time, you should pay attention to avoid repeated pressure and stimulation. If your nose is affected by pain and swelling, it is recommended that you go to the hospital in time to get a clear diagnosis and follow the doctor’s instructions for medication and treatment.
