Nosebleeds from picking the nose are more commonly caused by the tearing of the mucous membrane of the nasal cavity due to external forces when the patient picks the nose, thus inducing arterial bleeding from the lower part of the nasal cavity, which is more common in children, but also in adults. Most of the bleeding sites are in the nasal septal area, but some patients have deep nasal bleeding, which is not very common. In this case, the patient can first plug the nose with a cotton ball to see if the bleeding can be stopped. If there is still active bleeding, it is recommended to go to the hospital as soon as possible to have the nasal cavity plugged by the doctor or endoscopic electrocoagulation to stop the bleeding. After this treatment, the bleeding may stop in about 4 days when the local wound grows well. Patients are advised to use compound menthol nasal drops frequently to keep the nasal cavity moist to avoid drying out the nasal mucosa and inducing bleeding again. Patients are advised not to touch their nose as much as possible, keep their bowels open, eat more fruits, avoid constipation, avoid fire, etc.
