Do you find yourself regularly waking up with a headache? Or do you frequently experience discomfort in your face and neck? If so, you may be experiencing the symptoms of a common condition known as temporomandibular joint disorder, also called TMD. This condition leaves patients with chronic issues that affect the muscles of the face and the temporomandibular joint, which is the hinge that connects the jaw to the skull. You can feel this joint when you touch the back of your jaw near your ear and then open and close your mouth.
