In this case, it is usually suggested that the patient may have sinusitis, which is an inflammatory infection of the nasal cavity and sinuses and localized pus, resulting in the flow of purulent nasal discharge. Clinically, for this condition, it is recommended that the patient can go to an ENT clinic and have the doctor do a nasal endoscopy, and at the same time, a sinus CT examination can be done. If the diagnosis of sinusitis is confirmed, clinical antibiotics can be applied for oral symptomatic treatment, and oral mucus promoter can also be taken to promote the discharge of pus nasal mucus. At the same time, nasal spray hormone drugs and antihistamine nasal spray can be applied to promote the relief of nasal mucosal inflammation, and nasal irrigation can also be used clinically for treatment. In patients like this, if the condition does not heal for a long time and the history of the disease is particularly long, surgery can also be considered for treatment.
