Neck pain and a stiff neck
The levator scapula muscle located at the back and side of the neck connecting the neck with the shoulder is most affected. These muscles can be strained by everyday activities: for example, sleep in an awkward position, use a computer for a prolonged period, have a bad posture or have some sports injury such as swimming sudden fall, hold a phone between the neck and shoulder etc. Anxiety and stress can cause tension in the neck muscles leading to neck pain. Tight muscles are often chronic. Tight muscles block blood circulation of the body and muscles don’t get enough nutrition and become weak and easily get further damage. Because of blocked energy supply, you will feel tired all the time. Poor posture is a common cause of tight neck and shoulders. This causes overuse some groups of muscles and causes micro injury to the muscles which become tight to protect themselves from further injury. Furthermore the tight neck will make poor posture worse. It becomes a viscous circle.
