Your sinuses are hollow pockets behind your nose, eyes, and forehead that usually stay clear and filled with air. When you get acute sinusitis, the lining inside these pockets becomes inflamed, which means it gets red, swollen, and irritated.
This swelling blocks the drainage of mucus, a sticky fluid that normally flows out of your nose. When that fluid gets trapped, it creates a perfect environment for germs to grow, which causes the pressure and pain you feel in your face.
Common Symptoms
- A feeling of pressure or pain in your forehead, cheeks, or behind your eyes.
- A stuffy or congested nose that makes it hard to breathe.
- Thick, yellow or green mucus draining from your nose or down the back of your throat.
- A reduced sense of smell or taste.
- A dull headache or aching in your upper teeth.
- Fever or a general feeling of tiredness.
