Sinusitis

Sinusitis is an inflammation, or swelling, of the tissue lining your sinuses. Sinuses are structures inside your face that are normally filled with air. Bacterial infections, viral infections and allergies can irritate them, causing them to get blocked and filled with fluid. This can cause pressure and pain in your face, nasal congestion (a stuffy nose) and other symptoms. Sinusitis is also sometimes called rhinosinusitis.
