In any event, when the shoulder is elevated and the head is tilted, the result is a short upper trapezius (the muscle that extends from your shoulder to your neck) and a weak latissimus dorsi (the muscle that extends down the side of your back). The two are opposing muscle groups. The upper trapezius lifts your shoulders to your ears, while your latissimus dorsi depresses the shoulder and shoulder girdle directly downward.
The treatment in these cases would be to strengthen the latissimus dorsi and to stretch the trapezius on the side where tightness is experienced.
