Sinusitis is the inflammation of the sinuses. Often, sinusitis is caused by a cold or other upper respiratory virus. Sometimes, however, it is caused by bacteria. Most cases of sinusitis will resolve themselves, but occasionally a patient may need an antibiotic. Sinusitis that clears up within eight weeks and does not recur is referred to as acute sinusitis.
Common Symptoms
Acute bacterial sinusitis commonly causes uncomfortable nasal symptoms. These include stuffiness, congestion, and a thick yellow or green discharge. This causes a reduced sense of smell and taste. Feeling the discharge going down your throat is called post nasal drip, and is very common with sinusitis. Pressure in the forehead, around the eyes, or upper jaw can occur. A cough is also common with sinusitis.
Less Common Symptoms
Some cases of sinusitis will present with a low-grade fever, along with fatigue, irritability and general aches. Ear pain may occur from the sinus congestion. Bad breath and nausea are also possible symptoms of a bacterial sinus infection.
Symptoms Requiring Medical Care
While many cases of sinusitis will clear up on their own within several days, there are some symptoms that warrant a visit to your doctor. If your fever goes above 100.5, if the sinusitis gets better then returns, or if you are feeling worse instead of better after several days, call for an appointment.
There are also some symptoms that require emergency medical treatment. These include a red, bulging, or swollen eye, changes in vision, the inability to move the eye, a severe headache, swelling in the forehead, dilated pupils and personality changes. These may indicate an infection of the eye or the brain, and should be attended to immediately.
