The sinuses are air spaces located within the face and head.
Each of the 4 groups of sinuses has an opening which provides an outlet for the mucous to drain. This drainage is what allows your sinuses to remain clear. If there is anything that is obstructing the flow, it may lead to mucous buildup and therefore cause inflammation.
Signs and symptoms of sinusitis may include:
- Facial pain or pressure
- Discharge of yellow or green mucus from the nose
- Loss of the sense of smell or taste
- Bad breath
- Tooth pain
- Difficulty breathing through the nose
- Sore throat
- Ear pressure
