Shoulder and neck blockage is often caused by the following reasons: First, it is caused by prolonged braking. In today’s society, whether people are working or studying, they may sit or stand for a long time, which may lead to the gradual accumulation of meridians in the shoulder and neck area, and produce pain, stiffness and unfavorable movement. Secondly, it may be caused by cold in the shoulder and neck area, for example, if the patient blows the shoulder and neck area directly against the air conditioner, or if there is insufficient clothing, it will lead to cold in the shoulder and neck area, and then the meridians will be stagnant. Third, it may be caused by trauma to the shoulder and neck area, such as direct violence to the shoulder and neck area, or the effect of some long-standing injury, resulting in the blockage of blood, which then makes the meridians blocked. Fourthly, it may also be caused by excessive fatigue, such as excessive activity in the shoulder and neck area, which may also cause the meridians to be blocked, resulting in a series of symptoms.
