<p><strong>What Is Sinusitis?</strong></p>
<p>Sinusitis is an inflammation, usually due to infection, of one or more of the four sets of sinus cavities within each side of the facial skeleton. When irritated, the mucous membrane lining the sinus may swell and block the small drainage channels that permit mucus to flow into the nose. The buildup in pressure often results in headache, nasal congestion, drainage and facial pain. Acute sinusitis is a common disorder that often follows a cold or flu; chronic sinusitis refers to persistent or recurrent episodes that are generally milder than acute cases. Sinusitis often subsides on its own and responds well to home treatment. Rarely, infection may spread to the eyes or brain, possibly leading to vision loss, meningitis, or brain abscess.</p>
