How it's diagnosed
Clinical — no imaging needed unless complications suspected. Duration and pattern of symptoms guide antibiotic decisions.
Treatment
Saline rinses, decongestants (short-term), nasal steroids (fluticasone), and pain relievers. Amoxicillin-clavulanate for suspected bacterial sinusitis lasting >10 days or worsening.
