Common symptoms

What happens to your sinuses?

Even when you’re healthy, your respiratory tract makes more than a liter of mucus a day. You don’t even notice, because your body moves it out through your nose and throat. But with an infection, mucus thickens and increases, often getting trapped in your sinuses.


Infection can cause inflammation in the walls of your sinuses, making it hard to clear out mucus. Since your sinuses are in your forehead, cheeks, and behind your nose, you may experience pain in your face and head. Your sinuses are nearest your upper molars, which can also cause tooth pain.

  • Facial pain
  • Tooth pain
  • Headache


The color of your mucus doesn’t tell us whether your sinus infection is viral or bacterial, but it does tell us your body’s immune system is fighting something. If you’re experiencing an infection, the mucus is getting thicker – it’s collecting in your sinuses, causing more and more pressure.

  • Thick & colored discharge
  • Nasal blockage
  • Runny nose
