Sinusitis is an inflammation or infection of the sinuses. The sinuses are hollow spaces in the head that are lined with mucous membranes.
Sinuses usually drain properly, unless there is an inflammation or infection.
Sinusitis often develops following a cold and may also be associated with hay fever, asthma, or any air pollution that causes inflammation. It is most common in adults when the sinus cavities are fully developed, but can occur in infants and children. Take oral decongestants or use a decongestant nasal spray. Increase home humidity, especially in bedrooms. Breathe moist air from a humidifier.
