Headaches, Headaches, Everywhere!!!!
Headaches are one of the most common symptoms of a TMJ (Tempromandibular joint) problem and the number one reason for patients visiting their primary physicians. Tension headaches are the most common type of headache, and the TMJ headache is a tension type of headache. It is often described as a feeling of wearing a hat two sizes too small, with pain in a ring around the head, or as a migraine headache.
There are a few TMJ-related causes for tension headaches. Constant contraction of muscle fibers within a muscle, create tension, pressure or a tight feeling in the face and head, but constant tight muscle fibers prevent or reduce blood flow to that area. The body sends more blood to the areas and this can result an increase in general blood pressure to the muscles and head, sometimes referred to as vascular headaches. Clenching and grinding the teeth, which are TMJ symptoms, produce pain from the muscles in the head, which is a headache.
