Acute sinusitis is characterized by the inflammation of the nose & nasal passages that interferes with the normal drainage of the mucus in the sinuses. This causes difficulty in breathing with the throbbing sensation across the face, accompanied by headaches & nagging coughs.

Symptoms & Signs

Signs & symptoms associated with acute sinusitis may include fever, facial pain, nasal congestion, erythema, dental pain, cough, bad breath, nausea & sore throat.

Treatment: How to Treat "Acute Sinusitis"?

In most cases, the sinusitis will eventually subside without any need for antibiotics. However common treatment methods include, treating the allergy, use of decongestants, saline solution spray & antibiotics.


Sinusitis usually develops when the mucous membranes of the upper respiratory tract including the pharynx, nose, throat & sinuses becomes inflamed. This swelling will obstruct the openings of the sinus & prevent the mucus from draining naturally; creating a moist environment that makes it susceptible to infection. The primary cause of sinusitis is typically viral in nature, such as that of the common cold virus. Other triggers include allergies, a deviated nasal septum, nasal polyps & other medical complications.


Diagnosis of acute sinusitis typically involves a study of the patient's medical history, conducting a physical examination & perhaps using imaging studies as well as laboratory tests to get a definitive diagnosis. A CT scan can also be used to accurately pinpoint the areas of the inflammation.
