Tinnitus is a symptom that results from increased muscle tension in the face, jaws and neck. People with tinnitus can often affect their sound through jaw movements or by touching certain points of the face, jaws or throat/neck. (See animation).
Many indicate that tinnitus increases with increased stress. Muscle tension is a combination of stress and dental clenching/grinding. If you recognize yourself in this description, your tinnitus is likely to be somatic and thus treatable.
