What should you know about cough, runny nose, and congestion?

A Common Cold can swell the nasal lining, increase mucus, and cause drainage that prompts coughing. Allergic Rhinitis may cause congestion with sneezing, itch, and clear discharge. Sinusitis can cause facial pressure, reduced smell, or thicker mucus. COVID-19 and Influenza may include cough and nasal symptoms with fatigue, headache, or fever. House Dust Mite Allergy and Pet Allergy are possible when symptoms follow a particular indoor exposure. The symptom group alone cannot confirm its cause.

Rest and drink regularly. Saline spray or a suitable nasal rinse may loosen mucus; follow product instructions and use clean water as directed. Try a warm shower or humidified air for comfort, and sleep with your head slightly raised if drainage worsens the cough. Reduce smoke, dust, and animal exposure when these trigger symptoms. Ask a pharmacist before using decongestants, particularly with blood-pressure, heart, eye, or prostate conditions.

Seek emergency care for severe breathing difficulty, blue or grey lips, confusion, sudden chest pain, or severe swelling around an eye. Obtain prompt advice for dehydration, worsening facial pain, unusual drowsiness, or symptoms that keep intensifying. A clinician can assess breathing, ears, throat, and sinuses when home care is not enough.

Note when congestion began, whether one or both sides are affected, the colour and amount of discharge, exposure to dust or animals, and whether lying down changes the cough. Ask which treatment is appropriate for your pattern.
