This is for TMJ Disorder/Syndrome. TMJ means TemporoMandibular Joint, which is where the jaw attaches to the skull. This condition is actually a catch-all term for several issues that involve the joint, the jaw, and surrounding tissues - but doctors need a billing code, right? Lock-jaw, jaw pain, clicking, and even headaches are treated. This type of massage is a specialty, and properly requires an evaluation or assessment. Treatments can include a variety of massage for the muscles of the neck, head, and jaw, which sometimes includes intra-oral techniques (putting my gloved fingers into the mouth to reach internal muscles).
