Sinus infection, also known as sinusitis, is an inflammation of the sinuses that can be caused by viruses, bacteria, fungi, and allergens. The symptoms of a sinus infection can be similar to those of a cold, but they last longer and can be more severe. Common symptoms of a sinus infection include:
- Postnasal drip (mucus dripping down your throat)
- Runny nose with thick yellow or green mucus
- Stuffy nose
- Facial pressure (particularly around your nose, eyes, and forehead). This might get worse when you move your head around or bend over.
- Pressure or pain in your teeth
- Ear pressure or pain
- Fever
- Bad breath (halitosis) or a bad taste in your mouth
- Cough
- Headache
- Tiredness
If you have severe symptoms, or if your symptoms last longer than 10 days or keep coming back, it is important to see a doctor for a diagnosis. Because the cause of your sinus infection can affect your treatment options, it’s important to see a doctor for a diagnosis.
