Can The Temporalis Muscle Cause Pain and Headaches
A case study in the Journal of Oral Research helps explain how occasionally the tendon of the temporal muscle can be the source of pain. Tooth clenching or grinding, prolonged mouth opening, muscle strains, nail-biting, and trauma, such as whiplash, can create inflammation within the tendon leading to the pain you might feel. Your temporomandibular joint (TMJ), which connects your lower jaw to your skull, can also become inflamed within the chewing muscles, often due to teeth clenching or grinding. And according to a study published in BioMed Research International, those with TMJ disorder (TMD) often experience pain and soreness.
The pain and discomfort, however, sometimes travel beyond your jaw. When your temporalis muscle becomes inflamed, overworked, and tired, the pain can spread throughout your body — to your ears, shoulders, neck, and skull. According to the Cleveland Clinic, headaches can and do occur when it reaches the head, including the occasional migraine.
