Headache
TMJ muscles are found in the jaw and cheeks, so pain or tension from these muscles can extend to the top of your head. TMJ headaches are best described as tension headaches but the severity may vary from person to person. This symptom may last for a few days or more. Since it is the pain from the jaw and cheeks that spread to the head, this symptom can be managed or avoided by steering clear of all activities that can cause tension in the jaw and cheeks.
Muscle weakness and frequent fractures
TMJ can be described as a musculoskeletal and neuromuscular imbalance disorder. It can cause you to lose muscle control, limiting your movement. In an attempt to manage TMJ disorder, you may force your body into an unnatural position, which puts pressure on certain nerves, causing weakness or numbness [3] in parts of the body.
