Viral sinusitis condition guide: symptoms, causes, prevention, and when to seek care. Educational only — not a diagnosis.
Overview
Viral sinusitis occurs when cold viruses inflame the sinuses and trap mucus. It often follows a common cold and eases within about 10 days. Facial pressure and a blocked nose are typical.
Symptoms
- Facial pressure or pain
- Blocked nose
- Thick mucus
- Headache
- Temporary loss of smell
- Cough from post-nasal drip
Causes
Upper airway viruses are the main cause. Allergies, smoke, and prolonged nasal blockage can worsen it.
Treatment (general information)
Saline rinses, steam, rest, and short-term decongestants may help. Antibiotics are not needed for viruses. If symptoms last beyond two weeks, return to a clinic.
Prevention
Wash hands, treat colds early, avoid smoke, and manage allergies when possible.
When to see a doctor
Seek care for high fever, eye swelling, severe facial pain, or symptoms lasting beyond 10–14 days.
