Thank you so much for detail explanations . I did this techniques and noise decreased then suddenly increased very loud then became silent . Changing sound of ringing to silent high frequency . Have to continue to do it everyday . In neck and shoulders a lot of trigger points . I rub shoulder trigger points with tennis ball. Takes several weeks to get rid of them completely up to one month. In my right side of neck when I move left or right not spasm of blood vessels and arterial vein due to muscle spasm cause of trigger points causing dizziness .
