What causes a sore throat?

Pharyngitis (say: “fare-en-jy-tis”)—which is what your doctor calls a sore throat—can be caused by many things. Sometimes, when mucus from your sinuses drains into your throat, the drainage can make your throat feel sore. Viruses (such as those that cause the common cold) and bacteria (which can cause many illnesses, such as strep throat) can give you a sore throat. Your throat also may feel sore if you smoke, breathe polluted air, or drink alcoholic beverages. If you have hay fever or other allergies, a sore throat may be one of the symptoms.

How do I know what is causing my sore throat?
