What happens if a sinus infection goes untreated?

If a sinus infection goes untreated, it can become chronic (lasting over 12 weeks), worsen symptoms like congestion and facial pain, lead to loss of smell, or, in rare but serious cases, spread to the eyes (orbital cellulitis), brain (meningitis, brain abscess), or even cause sepsis, requiring urgent medical attention for potential vision loss, neurological damage, or death.

How do you know if your sinus infection is serious?

A sinus infection becomes serious when symptoms are severe, persistent (over 10 days), worsen after improving, or involve vision changes, confusion, high fever, severe headache, stiff neck, or trouble breathing, signaling potential spread to the brain, eyes, or bloodstream, requiring immediate ER care. While most clear up, these "red flag" signs mean it could be a severe bacterial infection or complication like meningitis, needing urgent treatment. 

How to tell if sinus infection has spread to the brain?
