Temporomandibular joint. That’s your jaw joint, but its acronym, TMJ, has become the short-hand term for problems associated with it. Clinically, it’s called TMJ Syndrome or Disorder, and often presents itself as a popping sound and sensation near the jaw joint.
TMJ Disorder symptoms take many forms, such as headaches, earaches, stuffiness, ringing in the ears, dizziness, numbness in fingers and arms, limited movement or locking of the jaw, and pain of many types (behind the eyes, in the face, back, neck or shoulders). In many cases, worn or cracked teeth are the only symptoms and pain does not occur until the disorder has advanced.
