Congestion headache: what to know

Inflamed nasal passages can create facial pressure around the cheeks, forehead or eyes, especially with a cold, allergic rhinitis or sinusitis. Chronic sinusitis may cause ongoing blockage, reduced smell and pressure rather than a sudden severe headache. Fever, body aches and fatigue can occur with common infections, including COVID-19. Dehydration, heat exhaustion and poor sleep can also cause headache while a dry environment makes nasal symptoms feel worse.

Not every headache felt during congestion comes from the sinuses. Migraine, tension, anxiety and other causes can overlap with a blocked nose. Dengue fever is relevant after possible mosquito exposure in an area where it occurs, particularly when fever, marked aches, rash or bleeding symptoms are present. A symptom combination cannot establish a diagnosis by itself.

Drink regularly, rest in a cool room and use saline spray or a gentle rinse for nasal mucus. Avoid very hot environments and take breaks from screens if they worsen the headache. A pharmacist can advise on a suitable pain reliever and congestion treatment, including important cautions for pregnancy, high blood pressure and other medicines. Follow the product directions and avoid repeatedly using nasal decongestant sprays without professional advice, because overuse can worsen blockage. Record triggers, temperature and associated symptoms if the pattern keeps returning.

Get urgent help for a sudden, extremely severe headache, new weakness or numbness, trouble speaking, confusion, fainting, a stiff neck, seizure, vision loss or repeated vomiting. Seek prompt medical advice for headache with high fever, a new rash, bleeding, severe dehydration, heat exposure or rapidly worsening illness. Arrange a review when congestion and facial pain keep returning, continue beyond a typical short illness, or affect sleep and daily activity. Extra caution is needed if you are pregnant, immunocompromised or recently travelled from an area with dengue activity.

Ask whether the pain pattern suggests sinus inflammation, migraine or another cause; whether you need testing; which medicines are safe for you; and what symptoms should trigger urgent review.
