A runny nose can be irritating, especially when it continues for days or weeks. While a common cold is a familiar cause, persistent nasal discharge can have several explanations.
1. Common cold: Viral infections often cause a runny nose, sneezing, congestion and sore throat.
2. Allergic rhinitis: Dust, pollen, mould and animal allergens can trigger sneezing, itching and clear nasal discharge.
3. Sinus inflammation: Inflammation of the sinuses may cause congestion, facial pressure and nasal discharge.
4. Non-allergic rhinitis: Strong smells, smoke, weather changes and certain foods can trigger nasal symptoms without an allergy.
5. Nasal polyps: These soft growths inside the nose can cause persistent congestion and reduced sense of smell.
6. Medication effects: Some medicines can cause nasal symptoms, while excessive use of certain decongestant sprays can lead to rebound congestion.
7. Structural problems: A deviated nasal septum or other anatomical issue may contribute to ongoing nasal obstruction and discharge.
What can help? Use saline nasal spray or a properly prepared saline rinse. For nasal rinses, use sterile, distilled or previously boiled and cooled water. Avoid inserting unprescribed substances into your nose.
If symptoms persist, are severe or repeatedly return, consult a healthcare professional. Seek urgent care for a severe headache, swelling around the eyes, vision changes or high fever with worsening symptoms.
Final thoughts: A runny nose is not always a cold. Identifying whether the cause is allergy, infection or another condition helps guide appropriate treatment.
