If your stuffy nose isn’t getting any better, you may have a sinus infection or sinusitis. Sinuses are air-filled spaces located behind cheekbones, on the forehead, and between the eyes. They’re responsible for creating mucus to keep your nose moist to protect against pollutants, allergens, and dust.
Sinus infections happen when these air-filled spaces become blocked and filled with fluid. This allows germs like viruses and bacteria to grow and cause an infection.
Risk Factors
Over 28.9 million Americans complain of a sinus infection at least once a year.
Factors that increase your risk of getting a sinus infection include:
- If you’ve had a cold previously
- Seasonal allergies
- If you smoke or have had exposure to passive smoking
- Structural differences or issues with the sinuses
- A weak immune system
