Sinusitis

[Renato]

Sinusitis is inflammation of the sinuses, most commonly caused by a viral or bacterial infection or by an allergy.

Some of the most common symptoms of sinusitis are pain, tenderness, nasal congestion, and headache.
The diagnosis is based on symptoms, but sometimes a computed tomography scan or other imaging tests are needed.
Antibiotics can eliminate an underlying bacterial infection.

Sinusitis is one of the most common medical conditions. Sinusitis may occur in any of the four groups of sinuses: maxillary, ethmoid, frontal, or sphenoid. Sinusitis nearly always occurs in conjunction with inflammation of the nasal passages (rhinitis), and some doctors refer to the disorder as rhinosinusitis. It may be acute (short-lived) or chronic (long-standing).
