Head cold without a runny nose: what to know

Cold symptoms vary from person to person. A virus may cause a scratchy throat, cough, tiredness, headache or mild fever while the nose feels dry or blocked rather than leaky. Swollen nasal tissue can narrow the airway even when little mucus is visible. Allergies may also cause congestion, throat clearing or itchy eyes without obvious discharge, especially after contact with house dust mites or pets. Influenza and COVID-19 can begin with throat, cough or whole-body symptoms rather than a runny nose. Sinusitis is more concerning when facial pressure, reduced smell, thick drainage or a worsening course develops.

Rest, drink fluids and avoid smoke or other irritants. Saline drops can moisturise the nasal lining; a gentle rinse may help blockage when performed with safe water and clean equipment. Keep the room comfortably humid rather than using very hot steam, which can burn skin and airways. Consider a home respiratory test when exposure or local guidance makes it relevant. A pharmacist can help choose symptom relief that matches your medicines and medical history.

Seek urgent help for difficulty breathing, chest pain, confusion, fainting, or inability to swallow fluids. Contact a clinician if symptoms become severe, steadily worsen, last longer than expected, or improve and then return strongly. Seek earlier advice if you are pregnant, immunocompromised, or have important heart, lung or other long-term disease.

Could nasal swelling explain the lack of discharge? Does my symptom combination fit a cold, allergy or another infection? Should I test for COVID-19 or influenza? Which decongestant or pain relief is safe for me?
