Numbness of the ear and face may be a sign of stroke. The American Stroke Association offers the F.A.S.T. warning signs to help you remember the signs of a stroke. They include Facial drooping, Arm weakness, Speech difficulty, and Time to call 911. If you or a person near you experiences sudden numbness or tingling on one side of the body, stroke may be the culprit. Additional symptoms are confusion and difficulty with understanding, vision problems, trouble walking, and an abrupt, severe headache.
3. Tooth Infection
An earache often signals an ear infection. However, an earache may also reflect pain that is occurring other parts of the body. An infected or impacted tooth can cause pain that radiates up into the ear. According to the American Association of Endodontists, an abscessed tooth is one in which the tissue inside the root canal of the tooth suffers inflammation and dies. This condition can cause pain and inflammation in your mouth and gums, and the pain can radiate to nearby structures, such as your ear canal.
Hearing loss that occurs in just one ear may be caused by a tumor on an auditory nerve. According to Johns Hopkins Medicine, an acoustic neuroma is a rare tumor of inner ear nerves. This benign tumor occurs when the body produces an excess of Schwann cells in the inner ear. These cells usually function to coat and protect nerves. When they grow out of control, they create pressure on nerves and can affect hearing and balance. In addition to hearing loss, other symptoms may be a feeling of pressure or fullness in the ear, problems with balance, and tinnitus.
