Sinus Infection Sinus Infection
Definition: A sinus infection is inflammation or swelling of your sinuses. Normally, your sinuses are filled with air. When the sinuses become blocked and filled with fluid, bacteria can grow there and cause infection. This infection is sinusitis.
Symptoms of a Sinus Infection • Thick, yellow, foul-smelling nasal discharge • Pressure or pain around the face and eyes • Headache (generally in the forehead area) • Nasal obstruction • Congestion • Post-nasal drip • A cold that won't go away or gets worse • Fever or cough
Different types of Sinusitis Acute sinusitis: 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. Subacute sinusitis: An inflammation lasting 4 to 8 weeks. Chronic sinusitis: A condition characterized by sinus inflammation symptoms lasting 8 weeks or longer. Recurrent sinusitis: Several attacks within a year.
How Sinusitis is Diagnosed To diagnose sinusitis, your doctor will review your symptoms and give you a physical examination. He or she may also tap your teeth to see if you have an inflamed paranasal sinus. Other diagnostic tests to assess the potential causes for sinusitis may include a mucus culture, nasal endoscopy (see below), X-rays, allergy testing, CT scan of the sinuses, or blood work.
