Chronic sinusitis is a common condition in which the cavities around nasal passages (sinuses) become inflamed and swollen for at least 12 weeks, despite treatment attempts.
Also known as chronic rhinosinusitis, this condition interferes with drainage and causes mucus buildup. Breathing through your nose might be difficult. The area around your eyes and face might feel swollen, and you might have facial pain or tenderness.
Chronic sinusitis can be brought on by an infection, by growths in the sinuses (nasal polyps) or by a deviated nasal septum. The condition most commonly affects young and middle-aged adults, but it also can affect children.
At least two of the four primary signs and symptoms of chronic sinusitis must be present with confirmation of nasal inflammation for a diagnosis of the condition. They are:
- Thick, discolored discharge from the nose or drainage down the back of the throat (postnasal drainage)
- Nasal obstruction or congestion, causing difficulty breathing through your nose
- Pain, tenderness and swelling around your eyes, cheeks, nose or forehead
- Reduced sense of smell and taste in adults or cough in children
Other signs and symptoms can include:
- Ear pain
- Aching in your upper jaw and teeth
- Cough that might worsen at night
- Sore throat
- Bad breath (halitosis)
- Fatigue or irritability
