Acute bacterial sinusitis is an infection of the sinuses caused by bacteria. It is usually caused by a virus, but can also be caused by bacteria. Symptoms of acute bacterial sinusitis include facial pain or pressure, nasal congestion, thick yellow or green nasal discharge, and a decreased sense of smell. Other symptoms may include fever, headache, bad breath, and fatigue. Treatment for acute bacterial sinusitis typically involves antibiotics, decongestants, and nasal sprays.
