Sinusitis
Sinusitis refers to an inflammation of the mucous membrane lining the paranasal sinuses. If often follows the common cold, influenza and other general infections. Germs which are usually eliminated from the body sometimes find their way into these sinuses or chambers on either side of the nasal passage, leading to a sinus trouble.

The sinuses consist of cavities or chambers contained in the bones situated in the head and face region. The frontal, maxillary, ethmoid and sphenoid sinuses are the paranasal sinuses which communicate with the nose. The frontal sinuses lie on the frontal bone directly above the eyes. The maxillary sinuses are located one on each side of the nose under the cheekbone. The ethmoid and sphenoid sinuses are situated behind the nose or either side of it. These air sinuses lighten the weight of the skull and give resonance to the voice.

Symptoms
The symptoms of sinusitis are excessive or constant sneezing, a running nose, blockage of one or both nostrils, headaches and pressure around the head, eyes and face. Sinus headaches are usually felt in the forehead and in the face just below the eyes. The patient may suffer from a low-grade fever, lack of appetite, loss of sense of appetite, and toothache. They may feel miserable because of difficulty in breathing. The voice is also affected because of the blocked nose.

Causes
Sinusitis results from the congestion of the sinus passages due to catarrh. It is caused by over-secretion of mucus in the membranes lining the nose, throat and head. This over-secretion is due to irritation caused by toxins in the blood.

A faulty diet can also cause sinus trouble. When a person consumes certain types of foods or drinks regularly, they have a conditioning effect on the entire system. As a result, some people persons become more sensitive to certain allergens, whose reaction ultimately turns into a sinusitis.
