Causes Of Tight Muscles In Neck And Shoulders. 1  Sporting activity: people who play sports such as tennis, badminton or athletes are susceptible to muscular strain and injury. Sport activities where the use of neck and shoulder muscle is more can lead to pulling of such muscles. Overstretching can cause spasm and restricted movement of neck and shoulder. Poor posture: neck and shoulder tightness is also a reason of poor posture. Sitting in front of a computer for long hours can put stretch and strain on muscles of shoulder and neck.
Since the muscles are not designed to be under constant stress, it is extremely essential that the stress or load is taken off as the muscles relax in the passive mode. If any activity acts as a trigger and causes the neck muscles to stay under constant tension, one is most likely to develop tension knots. Though some practitioners cite the accumulation of abnormal protein deposits within the muscle tissue as the triggering factor behind the development of muscle knots in the neck area, this theory has not been corroborated by medical research.
