Most sinus infections start out as viral infections, against which antibiotics are useless. But after seven to 10 days, about 60 percent become bacterial infections. Even then, most will heal on their own. But antibiotics may speed healing. Here are some symptoms that may indicate a bacterial infection:
· Infection lasts for more than a week to 10 days
· Fever higher than 101 degrees
· Facial pain or pain in the upper teeth
· Lessening, then worsening of symptoms
· Dark, thick, yellow-green nasal discharge
