By lying on the sofa in the same positon repeatedly, three areas of the neck are affected most by pain. They are the the dorsal scapular nerve,the Scalenus medius muscle and the Levator scapulae muscle. When there's repetitive pressure on a muscle, they shorten,which is called 'isotonic contraction'.This results in pulling at the muscle's origin and insertion leading to inflammatory pain.
