What should you know about severe sinus infection?

Sinusitis is inflammation of the spaces around the nose. Swelling can narrow the drainage openings, allowing mucus to build up and making the nose feel blocked. Facial pain or pressure may be felt around the cheeks, forehead or eyes. A cough, earache or fever can occur as nearby areas are irritated. A common cold or allergic rhinitis can precede sinus symptoms, but symptoms can also develop without an obvious trigger.

Rest, drink fluids and use saline spray or a gentle saline rinse if it is suitable for you. Warm moisture may ease thick mucus, while avoiding smoke and other irritants can reduce further inflammation. Take pain or fever medicine only as directed on the label and check with a pharmacist if you have another illness or take regular medicines. Do not start leftover antibiotics; a clinician can decide whether treatment is appropriate after considering the pattern and duration of symptoms.

Arrange prompt medical advice if severe pain, fever, or thick discharge is getting worse, if symptoms are not settling, or if one-sided symptoms are pronounced. Seek urgent help for swelling or redness around an eye, changes in vision, severe headache, confusion, a stiff neck, repeated vomiting, or difficulty breathing. These signs can indicate spread beyond the sinuses or another condition needing immediate care.

Ask whether your symptoms fit sinusitis, whether an examination is needed, which medicines are suitable with your health history, and what change should prompt review. Mention any eye symptoms, dental pain, recent cold, allergies or repeated episodes.
