For non-stop runny nose, it can be considered as acute rhinitis caused by viral infection. The main manifestations are sneezing, nasal congestion, and clear water-like nasal discharge, and this postnasal drip sensation and virus-induced inflammatory mediators lead to the hypersensitivity of the afferent nerves in the upper respiratory tract, resulting in non-stop runny nose. 2-3 days later, the nasal discharge will become sticky, and at the same time, there may be a dull taste, poor breathing, and sometimes pharyngotonsillitis, resulting in hearing loss. After drinking water for a few times, it can be cured in 5-7 days. If there are complications, the condition may be relatively prolonged. For the symptoms of non-stop runny nose, the nasal cavity can be rinsed by nasal washer, and the edema of nasal mucosa will be obviously reduced, and the symptoms of runny nose will also be reduced.
