Bleeding from nasal mucosa can be treated effectively and recovery is usually gradual in 1-2 weeks. There are many causes of nasal mucosal bleeding, such as dry nasal cavity, allergy, cold and flu, or frequent picking and rubbing of nasal cavity can cause nasal mucosal bleeding. If the bleeding is mild, local medications to moisturize the mucous membrane, such as caryophyllene nasal drops and compound peppermint oil nasal drops, can be used, and the mucous membrane erosion usually returns to normal after 2 weeks. If the nasal mucous membrane bleeding is more intense, patients need to go to the ENT department of the hospital for nasal cavity stuffing treatment in time. If the site of nasal mucosal bleeding is clear, physical cautery and radiofrequency treatment such as plasma is recommended. In addition, if the patient has recurrent nasal mucosa erosion and bleeding, routine blood and coagulation tests are needed to exclude hematologic disorders. Patients should avoid picking their nose in daily life and develop good hygiene habits, which can effectively prevent nasal mucosal erosion and bleeding.
