Thanks for all the replies guys, that stretch looks really good too. I'm thinking everything is at its worst right when I wake up as I tend to sleep in a very posture compensating position (on stomach, right shoulder rolled forward, head tilted up and to the left, mouth wide open) that maybe if I did some sort of stretching routine right upon waking, it would set better posture for the rest of the day. But I just know that until I get my jaw fixed and airway opened up, my body will continue to sacrifice my posture for lack of airway space. My airway is only 3mm in diameter :/
I emailed Arnetts office asking this question and their advice about who to see. I figure they've dealt with plenty of patients similar to me so we'll see what they advise.
