Sinus Infection:

Sinus infection is the swelling or inflammation of the tissue that lines the sinuses. Normally, sinuses are filled with air, but when sinuses become blocked and filled with fluid, germs can grow and cause an infection. Conditions that can cause sinus blockage include the common cold, allergic rhinitis, nasal polyps, or a deviated septum.

There are four different types of Sinus Infections. They are:

(1) Acute Sinus Infection – a sudden onset of cold-like symptoms such as runny, stuffy nose and facial pain that does not go away after 10 to 14 days. Acute sinusitis typically lasts 4 weeks or less.
(2) Subacute Sinus Infections – sinus inflammation lasting 4 to 8 weeks.
(3) Chronic Sinus Infection – sinus inflammation symptoms lasting 8 weeks or longer.
(4) Recurrent Sinus Infection – several attacks within a year.
