The middle of the back pulling pain when lowering the head, this situation is mainly due to two reasons: First, because of the frequent head down, and bilateral elbow position continues to hang, no support, resulting in the middle of the back position of the scapular raphe, small rhomboid muscle, large rhomboid muscle, continue to be in a state of fatigue tension, local muscle strain, and will lead to muscle inflammatory edema state, in the low head of When this position of the muscle is pulled, stimulated, there will be obvious pulling, painful feeling. Second, because the pillow is too high at night when sleeping, so that the cervical vertebrae are in a state of forward leaning, will also lead to the back muscles in a state of tension and fatigue; in addition, the back is prone to cold at night, will lead to more muscle tension, resulting in the gradual accumulation of inflammatory metabolic products, can not get sufficient metabolism and absorption, will stimulate the peripheral nerves, the same will appear local inflammatory edema, pain. The same local inflammatory edema and pain will occur, especially when the head is lowered, which will also pull on the inflammatory lesion, leading to further increase in pain.
