When nasal reflux patients mainly show that their noses are often not ventilated and they have a lot of nasal mucus, but they always feel that it cannot be drained. When the patient tilts his head or lies on his back, a lot of pusy nasal mucus often flows into his throat, and he often coughs up a lot of yellow mucus and foul sputum, and sometimes the patient can’t help but have the symptoms of nausea and foreign body feeling in his throat. The main reason is that the backflowing nasal discharge stimulates the mucous membrane of the patient’s throat. It is recommended to go to the hospital to take a sinus CT to clarify the specific situation in the sinuses. If it is caused by sinusitis, oral Oronema drops should be taken to promote the outward discharge of nasal mucus, and the symptoms of nasal reflux will be improved after active and symptomatic treatment.
