Q: CAN MY EAR PAIN BE CAUSED BY MUSCLES?
A: The short answer is YES! The sternocleidomastoid is a thick muscle that extends from just under the ear down to the collarbone. Injuries to this muscle can cause jaw and ear pain, as well as sinus pain, eye pressure, and other symptoms that a person might mistake for signs of a cold or infection. When a person has these symptoms but has no injuries and no other signs of infection — such as a fever or runny nose — an injury to the sternocleidomastoid may be the culprit. A doctor can rule out other causes, such as infections of the middle or inner ear, by carrying out a physical examination.
