Acute neck pain is very common and usually nothing to worry about. There is often a link be-tween neck pain and tense muscles, for instance after working at a desk for a long time, poor posture, prolonged use of a computer, or sleeping in an awkward position. But neck pain may also arise without an identifiable cause. It usually goes away within about one to two weeks. In some people it comes back again in certain situations, such as after work or intensive sports. Neck pain is considered to be chronic if it lasts longer than three months.
