Sinus problems are very common. A condition called Sinusitis occurs when the sinus passages become inflamed and infected usually because they are blocked. The blockage makes it difficult to breath. Pain, fever and a yellow or green nasal discharge are also signs of sinusitis. The nasal discharge often causes a sore throat and affects your chest making you cough.

Your sinuses are four air pockets behind the facial bones. The frontal sinuses are over the eyes in the eyebrow area. The maxillary sinuses are behind each cheekbone. Just behind the bridge of the nose and between the eyes are the. Located behind the ethmoids, the sphenoids are in the upper region of the nose and behind the eyes.

The human head is made to provide both the ability to hear with both ears and the ability to see with both eyes at the same time. If these spaces were filled in with solid bone, your head would be too heavy, and your neck could not support it. The air spaces or sinuses are lined with mucus membranes. This is damp, delicate tissue covered with tiny hairs called cilia which are coated with mucus. The mucus is your body’s defense against particles and bacteria in the air you breathe.

The cilia pulse at a determined rate moving the mucus through your nose and sinus passages. This happens very fast between 14-16 pulses per second, and it takes from 5 to 8 minutes to move mucus from the nostrils to the back of your nose into your throat. The bacteria trapped in the mucus is swallowed and broken down in your stomach. These same microscopic hairs are present inside your chest where they do the same work of moving bacteria and toxins out of the chest to be disposed of in the stomach.

All four sinus cavities have an opening into the nose. This allows air and mucus to flow in and out for drainage. Each sinus is also joined to the nose by the same mucus membrane. A nasal infection or an allergic reaction may also trigger sinus problems.

Your nasal and sinus passages are very narrow. If the mucus membranes become swollen, they overproduce mucus. Too much mucus fills in the narrow passageways of your sinus cavities and may completely block them. The cilia may also become overwhelmed by the increased amount of mucus and be unable to keep it moving normally. When either of these two things happen, pressure builds up inside your sinuses causing pain. The bacteria within the mucus can multiply and become infected resulting in sinusitis.

Sinus problems often cause sinus headaches.
