Nose dripping water may be upper respiratory tract infection, allergic rhinitis, cerebrospinal fluid leakage, etc., should be timely consultation to find out the cause of the disease. 1. Upper respiratory tract infection: when pathogens invade the upper respiratory tract, it will cause the mucous membrane of the upper respiratory tract to become congested, edematous, and increase secretion. Upper respiratory tract infection can lead to dripping watery nasal mucus, accompanied by dry pharynx, sore pharynx, nasal congestion, sneezing, and low-grade fever. 2. Allergic rhinitis: It is an inflammation of the nasal mucosa caused by the release of inflammatory mediators, immunoreactive cells and cytokines mediated by IgE in atopic individuals exposed to allergens. It can lead to symptoms such as water dripping from the nose, itchy nose, sneezing and so on. 3. Cerebrospinal fluid leakage: Most of the patients have cerebrospinal fluid leakage due to cranio-cerebral trauma caused by fall or collision, which is manifested as water dripping from the nose due to the defect of the base of the skull, and the cerebrospinal fluid flows into the nasal cavity from the defect site. There may be other reasons for the water dripping from the nose, so you should consult a doctor in time to find out the specific cause and get appropriate treatment if necessary.
