Allowing a sinus infection to go untreated can lead to serious complications. Untreated sinusitis can spread to surrounding structures such as the brain, leading to meningitis or brain abscess, which are life-threatening conditions. It could also lead to chronic sinusitis, where symptoms persist for months or even become recurrent. In some cases, it can cause vision problems or infections in the bones (osteomyelitis). Seeking medical treatment early on is essential to prevent these serious outcomes.
