With green nasal discharge, the patient is considered to have sinusitis, which may be a combination of viral bacterial and other infections, resulting in an inflammatory infection of the patient’s nasal cavity and sinuses. Once this condition occurs, the patient is advised to go to an ENT clinic for a nasal endoscopy and also a sinus CT to check the severity of the sinusitis. If the history is relatively short and it is acute sinusitis, you can apply antibiotics for a short period of time. The choice of antibiotics can be better by first doing bacterial culture of the secretions and choosing sensitive antibiotics for treatment. At the same time, apply mucus promoter to promote pus nasal discharge, nasal spray hormone to relieve nasal inflammation and ventilation, and do nasal flushing, which can flush out a large amount of yellow pus nasal discharge. For acute sinusitis patients treated for 15-31 days, the symptoms are significantly improved. If the patient has a long history of the disease, medication for more than a month, and still no effect, surgery can be considered. If the nasal discharge is green, other diseases are not excluded. In some patients, especially small children, with nasal foreign bodies, local infection of nasal foreign bodies may cause patients to develop green nasal mucus. Individual patients with tumors inside the nose and nasal cavity and diffuse local ulcer infection of the tumor may also have green nasal discharge. So in a word, for such a case, it is recommended that patients should go to ENT department for systematic examination and then choose a reasonable treatment plan according to the kind of disease.
