Roughly 37 million Americans have at least one sinusitis attack annually, according to WebMD. And they're not fun. Sinusitis is an irritation, swelling or infection of the tissue lining the sinuses. The illness typically causes facial pain and pressure; nasal stuffiness or discharge, often coupled with post-nasal drip; loss of smell; and a cough. Sometimes patients develop a fever and their teeth ache, due to the pressure in the sinus cavities above.
When infection is present, you'll often have a thick, yellow or green nasal discharge along with some of the other symptoms mentioned above. Head to the doctor; you'll need an antibiotic to get rid of the infection. Besides prescribing an antibiotic to take care of the bacterial infection, your doctor may prescribe nasal sprays, nose drops or an oral decongestant medicine to relieve the symptoms.
