I think that was what a friend was talking about doing for his tinnitus he'd flick with his finger behind his ear & said it really helped. Hey! Can't hurt to try!
I posted this more for relaxation technique. Many people are uptight and don't even realize it. If you don't sleep well, good chance this can help you get good rest and feel better, which makes for a better dowse. Just thought there was some good info here. but many other youtube videos.
