What should you know about persistent nasal drip and cough?

Mucus draining from the back of the nose can tickle the throat and trigger repeated throat-clearing or coughing, often more noticeably at night or when lying down. Allergic Rhinitis and Common Cold can increase nasal secretions. Acid Reflux can irritate the throat without obvious heartburn, while Asthma can cause cough, wheeze, or chest tightness. Acute Bronchitis, Chronic Cough, Bronchiectasis, and Bronchiolitis may also be considered depending on age, duration, breathing symptoms, and past illnesses.

The colour or thickness of mucus alone does not identify the cause. Tell a clinician whether the drip is seasonal, whether the cough is dry or brings up phlegm, and whether exercise, cold air, meals, or lying down changes it.

Keep fluids nearby, avoid smoke and strong fragrances, and use a saline nasal rinse or spray only as directed and with safe water. Elevating your head slightly at night may reduce drainage and reflux-related irritation. Note triggers, sleep disruption, wheeze, breathlessness, fever, and any medicines. A pharmacist or GP can advise whether an allergy treatment or another approach fits your symptoms. Avoid starting antibiotics or using decongestant sprays for longer than the product instructions without advice.

Seek urgent help for severe breathlessness, blue or grey lips, chest pain, coughing blood, confusion, fainting, or sudden worsening. Arrange prompt medical review for persistent fever, unexplained weight loss, night sweats, recurrent chest infections, noisy breathing, or a cough that is steadily worsening. Children, older adults, pregnant people, and anyone with significant lung or heart disease may need earlier advice. A lingering cough that disturbs sleep or daily activity deserves assessment even when the nasal drip seems mild.

Could the cough be coming from my nose, reflux, asthma, or the lungs? Do I need an examination of my nose and chest or any testing? Which nasal products are suitable for me? What should I do if breathing symptoms or fever appear?
