Differentiate from infection: purulent discharge and fever suggest rhinosinusitis. Unilateral obstruction with bloody discharge raises concern for a foreign body. Facial pain and thick yellow discharge point to bacterial sinusitis.
Allergic shiners (dark circles under eyes) and a nasal crease from frequent rubbing support the diagnosis. Always inspect the nasal mucosa directly; pale, swollen turbinates are a hallmark sign distinct from the erythematous mucosa of an infection.
