Why TMJ Disorder Causes Headaches
There can be a number of reasons for a headache. But when the jaw is out of alignment, this can cause pressure that radiates to your ears, sinuses, and throughout your head. It can also cause shoulder, neck, and back pain.
Headaches are often blamed on stress. When stressed, many people clench their jaw. When your jaw is already out of alignment, clenching can increase this pain significantly.
