One of the most common nasal and sinus conditions is sinusitis, also known as a sinus infection. This is a swelling or inflammation of the tissue that lines the sinus and nasal area. Sinusitis can be the result of a bacterial infection, virus, or structural issues like narrow sinus openings or facial injury. If the sinus opening is too narrow, normal mucus drainage may not occur, leading to congestion and infection.
A normal sinus cavity is filled with air. But when the sinus tissue is irritated, the cavity can become blocked and fill with fluid, which can lead to an infection. Colds, allergies, nasal polyps or a deviated septum can all cause sinus blockages.
Sinusitis is many times an acute condition which can be treated with nasal saline rinses, antihistamines, and over the counter decongestants. However if the symptoms of sinusitis last more than eight weeks or recur throughout the year, you may be experiencing chronic sinusitis.
