How Is It Treated?
Acute viral: nasal saline irrigation, decongestants, analgesics. Bacterial (>10 days or worsening): amoxicillin-clavulanate 5-7 days. Intranasal corticosteroids for chronic sinusitis.
Tests and Imaging Typically Needed
Clinical diagnosis primarily. CT sinuses for complications or chronic disease. Allergy testing for recurrent sinusitis.
