The condition is also common in clinical practice and is often diagnosed as a drop pillow, mostly when rising from sleep. Falling pillow is a generalized diagnosis. There are several groups of muscle injuries that can be diagnosed as a falling pillow. Sternocleidomastoid tendonitis, only one kind of pillow. This disease is considered by all Chinese doctors to be a wind-cold attack on the tendons and a strong neck. Western medicine believes that when the tendon of aseptic inflammation. The tendon is in constant repair, and the head activity is frequent during the day, so that the tendon keeps moving. Because of its good blood flow and fast metabolism, the local blood flow of the tendon becomes poor and metabolism slows down after sleep because of the cessation of head activity, plus sometimes poor sleep posture, which aggravates the strain injury of the sternocleidomastoid muscle. If coupled with poor neck warmth, the tendon is stimulated by cold, making the blood flow worse, so that the necrotic cells and exudates in the injured part of the tendon cannot be metabolized and eliminated, forming edema. The disease develops by stimulating the nerve endings. Phenomenally it is a new disease, but in essence it is a new onset of old disease caused by accumulative strain injury. Therefore, small acupuncture has obvious effect on this disease as well.
