Does your head always feel stuffy? Do you have discolored nasal drainage? Do you often feel pain and pressure behind your eyes and cheeks? If you answered "yes", you're in good company. About 35 million people develop chronic sinusitis each year, making it one of the most common health complaints in America.
What is sinusitis?
Sinusitis is an inflammation of the nasal sinuses which are air pockets in the skull between the facial bones. There are several of these large sinuses, which include:
- Maxillary - the two inside the cheekbones
- Frontal - the two above the eyes
- Ethmoidal and Sphenoidal - the four in the middle of the face and head
The sinuses are lined with membranes that secrete antibody-containing mucus, which protects the respiratory passages from the onslaught of irritants in the air we breathe.
