Sinus Infection (Sinusitis) Symptoms and Treatment Options

What is a sinus infection or sinusitis?

Inflammation of the air cavities within the passages of the nose (paranasal sinuses) is referred to as sinusitis. Sinusitis can be caused by infection (sinus infection), but also can be caused by allergy and chemical irritation of the sinuses. A sinus infection (infectious sinusitis) occurs when a virus, bacterium, or a fungus grows within a sinus.

Sinusitis is one of the more common conditions that can afflict people throughout their lives. Sinusitis commonly occurs when environmental pollens irritate the nasal passages, such as with hay fever. Sinusitis can also result from irritants, such as chemicals or the use and/or abuse of over-the-counter (OTC) nasal sprays, and illegal substances that may be snorted or inhaled through the nose. About 30 million adults have "sinusitis." Colds differ from sinusitis and are only caused by viruses and last about 7 - 10 days while sinusitis may have many different causes (infectious and non-infectious), and usually last longer with more pronounced and variable symptoms.
