Chronic sinusitis complications include:

  • Asthma flare-ups. Chronic sinusitis can trigger an asthma attack.
  • Meningitis. This infection causes inflammation of the membranes and fluid surrounding your brain and spinal cord.
  • Vision problems. If infection spreads to your eye socket, it can cause reduced vision or even blindness that can be permanent.
  • Aneurysms or blood clots. Infection can cause problems in the veins surrounding the sinuses, interfering with blood supply to your brain and putting you at risk of a stroke.
