Chronic nasal congestion and post-nasal drip

Congestion narrows the nasal passages, while post-nasal drip describes mucus moving down the back of the throat. Allergic rhinitis may bring sneezing, itching, and watery discharge; house dust mites can be a trigger. Sinus inflammation may add facial pressure, reduced smell, thick mucus, or an unpleasant taste. A common cold usually improves as the infection settles, whereas symptoms that continue or repeatedly return need a broader review. Night-time blockage can contribute to mouth breathing, throat irritation, snoring, or poor sleep. These symptoms do not identify one cause by themselves.

Notice when symptoms flare and record possible triggers such as dust, pets, smoke, strong scents, or changes in weather. Saline nasal rinsing may help clear mucus; use sterile, distilled, or previously boiled and cooled water with clean equipment. Drink enough fluid to keep secretions comfortable, and avoid smoke exposure. A clinician or pharmacist can advise whether allergy medication or a nasal treatment fits your symptoms and how to use it correctly. Do not keep using a decongestant nasal spray beyond its labelled period, because rebound blockage can develop. Arrange a medical review if symptoms affect sleep, smell, work, or daily activities.

Seek urgent help for severe breathing difficulty, swelling around the eyes, confusion, a severe headache with fever, or sudden swelling of the face or throat. Book a prompt appointment for one-sided persistent blockage, repeated nosebleeds, worsening facial pain, high fever, or symptoms that are steadily worsening. A clinician can examine the nose and throat, review medicines and triggers, and decide whether further testing is needed.

Ask: Could allergy, sinus inflammation, or another nasal problem explain this pattern? Which treatment should I try first, and for how long? How should I perform a saline rinse safely? Does my night-time blockage need assessment for a sleep-related breathing problem?
