Myofasciitis, also known as “low back muscle injury”, “low back fibrositis”, “low back fascial pain syndrome”, etc., refers to the aseptic inflammatory reaction of muscles and fascia. The acute onset of myofasciitis can be triggered when the body is stimulated by external factors such as wind and cold, fatigue, trauma or improper sleep position, etc. Acute or chronic injury or strain to the muscles, ligaments and joint capsule of the low back is the basic cause of the disease. As a result of the acute phase is not thoroughly treated and becomes chronic; or due to repeated strain, wind and cold and other adverse stimuli, the patient can repeatedly experience continuous or intermittent chronic muscle pain, soreness and weakness. Muscles and ligaments are the power base of various activities of the body, and their end devices are the bones where their muscles are attached, which are the power transmission hubs that drive bones and joints, and are also the parts where stresses are concentrated and intersected, so they are very easy to be injured. Repeated injury to the local muscle, when the injury healed can leave scars or adhesions, scar tissue can reduce the number of local blood vessels or small diameter, the occurrence of local microcirculation blood flow regulation ability to reduce the muscle blood supply and anaerobic work ability to lose. The local ischemia of the muscle causes pain due to peripheral nerve stimulation, and the patient cannot tolerate prolonged physical activity or even sedentary activities. For example, long-term incorrect posture can cause physiological contracture of local muscles, long-term repeated muscle spasm causes muscle ischemia, sterile exudation, scar formation, local myofascial often subjected to postural load and extreme tension, fatigue causes postural injury, repeated exertion causes muscle micro-tear injury, pain-causing substances around the myofascial microvascular reaction zone, long-term formation of pain-sensitive points or painful muscle hard nodes. In the acute phase of myofasciitis of the low back, patients have severe pain in the low back, a burning sensation, increased symptoms during lumbar activities, significant local pressure pain (mostly at the starting and ending points of the lesioned muscles), some patients have increased body temperature, and blood tests show increased white blood cells. After an acute attack, a few patients’ symptoms may subside completely, but most of them may have pains that may reoccur months or years later. Chronic cases are characterized by lumbar pain, muscle stiffness, and a feeling of heaviness, often aggravated by changes in weather (such as rainy days), at night, or in humid areas. The lumbar pressure pain is widespread, and the lumbar functional activity can be normal, but the lumbar pain is obvious when moving.
