For many of us, sitting long hours before the desk can make the neck and back muscles stiff. The head is heavy — about 7-10 kilograms; keeping the head leaning forward stresses the neck and shoulder muscles.

Sometimes, overworking a muscle may cause small portions of the muscle to contract involuntarily and remain tight. The wad of muscle fibers staying in a hard contraction is called a trigger point. The tiny muscles, shortened and tightened by trigger points, can pull individual vertebrae out of place. The compressed intervertebral discs  pinch the nerves, causing numbness and pain in the neck and shoulders.

It would be great if you could get a professional to massage those trouble spots, but they cost money. It would be great if you could do it yourself.
