Arm and Shoulder Pain

when there is too much tension in the shoulder girdle it causes the muscles to be sore, and it decreases the range of motion in the arm due to the shortness of these muscles. A muscle tear in one of these muscles causes too much pain when trying to lift an object or when trying to lift your arm above the neck.

Pain in the Arm can be caused by an obstructed nerve or too much tension in the muscles making them inflamed.
