ComplicationsBy Mayo Clinic staff
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.
