Signs and symptoms of<unk><unk>  disorder vary in their presentation. The symptoms will usually involve more than one of the various components of the masticatory system, muscles, nerves, tendons, ligaments, bones, connective tissue, or the teeth. The three classically described, cardinal signs and symptoms of<unk>  are: * Pain and tenderness on palpation in the muscles of mastication, or of the<unk>  itself (preauricular pain – pain felt just in front of the ear). Pain is the defining feature of<unk>  and is usually aggravated by manipulation or function, such as when chewing, clenching, or yawning, and is often worse upon waking. The character of the pain is usually dull or aching, poorly localized, and intermittent, although it can sometimes be constant. The pain is more usually unilateral (located on one side) rather than bilateral. It is rarely severe. * Limited range of mandibular movement, which may cause difficulty eating or even talking. There may be locking of the jaw, or stiffness in the jaw muscles and the<unk> s, especially present upon waking. There may also be incoordination, asymmetry or deviation of mandibular movement. * Noises from the<unk>  during mandibular movement, which may be intermittent.<unk>  noises may be described as clicking, popping, or crepitus (grating). TMJ<unk>  is commonly associated with symptoms affecting cervical spine<unk>  and altered head and cervical spine posture. Other signs and symptoms have also been described, although these are less common and less significant than the cardinal signs and symptoms listed above. Examples include: * Headache (possibly), e.g. pain in the occipital region (the back of the head), or the forehead; or other types of facial pain including migraine, tension headache. or myofascial pain. * Pain elsewhere, such as the teeth or neck. * Diminished auditory acuity (hearing loss). * Tinnitus (occasionally). * Dizziness. * Sensation of malocclusion (feeling that the teeth do not meet together properly).
