A cold lasting 10 days turns into facial pain with purulent discharge — acute bacterial sinusitis. Viral URI → sinus ostia blocked → bacterial superinfection (pneumococcus, H. influenzae): facial pain/tenderness, purulent rhinorrhea, >10 days or double-worsening → amoxicillin. Chronic (>12 weeks — polyps, deviated septum blocking drainage): FESS opens ostia. Complications — orbital (periorbital swelling — emergency), intracranial (frontal — meningitis/abscess). Epistaxis: anterior (Little's area — pinch 10 min, lean forward) vs posterior (elderly hypertensive — packing/balloon). The lingering cold is the clue — 10 days of facial pressure means bacteria.
