Over 37 million people suffer from chronic sinusitis. Sinusitis (also called rhinosinusitis) is the name of the condition in which the lining of the sinuses becomes inflamed.

The sinuses are air spaces behind the bones of the upper face, between the eyes and behind the forehead, nose, and cheeks. Normally, the sinuses drain through small openings into the inside of the nose. Anything that blocks the flow can cause a buildup of mucus; the blockage can cause inflammation and possibly infection.

Common Symptoms of Sinusitis include:

• Facial pain, pressure, congestion, or fullness
• Discharge of yellow/green mucus from the nose
• Pain in the teeth
• Loss of smell or taste
• Headache
• Fatigue
• Sore throat
• Bad breath
• Fever and/or coughing

Sinusitis is typically treated first with medication, such as antibiotics or nasal steroid sprays. Inhaling steam or using nasal saline sprays may also be helpful. However, at least 20% of patients do not respond to these medications or treatments.
