What should you know about non allergic rhinitis cough?

Nasal swelling can change airflow, while mucus draining behind the nose can irritate the throat and trigger repeated clearing or coughing. The cough may be worse when lying down, after exposure to perfume or smoke, or during cold-air changes. A dry cough can also come from asthma, reflux, a recent infection, or a medicine, so the presence of nasal symptoms does not identify the cause by itself. A runny nose, sneezing and throat sensation point toward an upper-airway contribution; wheeze, chest tightness or breathlessness require attention to the lower airways.

Notice whether the cough follows nasal drainage, meals, lying down, exercise or a specific irritant. Avoid smoke and heavily scented products, drink fluids according to your usual medical advice, and consider gentle saline nasal care. Do not use leftover antibiotics or extend a decongestant spray beyond its directions. Arrange a review if the cough continues, disturbs sleep or affects daily activity. A clinician can examine the nose and chest, review medicines and consider [Chronic Cough](/conditions/chronic-cough/) or [Asthma](/conditions/asthma/) when appropriate.

Seek prompt medical advice for a cough that is persistent, worsening, associated with fever, facial pain, foul-smelling mucus, repeated vomiting or unexplained weight change. Get urgent help for coughing blood, severe breathlessness, chest pain, blue lips, faintness or sudden deterioration. A child, older adult or person with significant lung disease may need earlier review when breathing symptoms appear.

Could mucus drainage explain my cough, or should my chest be checked? Which nasal care is suitable? Could a medicine, reflux or asthma contribute? What symptoms mean I should seek urgent help?
