Sore throat and ear pain are often connected to each other and may be caused by a bacterial or viral infection. Other causes of these issues include allergies, drinking too much alcohol, infections of the teeth, or a uvula infection. Issues with the sinuses also can cause problems between the throat, nose, and ear. Severe problems can also be a sign of head or neck cancer.
The throat and ears are located closely beside each other, so many times a problem with one of these areas will cause problems in the other. A bacterial or viral infection that occurs in the throat or ear can cause sore throat and ear pain and the development of the same infection in the other area. Often, one side of the throat can be infected and cause the ear on the same side to become infected as well, while the other side the throat and the other ear remain untouched.
