Lumbar muscle strain is a kind of lumbar disease known to everyone, which is actually a chronic lumbar strain. It is mainly caused by two kinds of reasons, one is the acute lumbar sprain, failure to timely and reasonable treatment, thus causing chronic lumbar muscle traumatic scar and adhesion formation, weakening the strength of the lumbar muscle, thus causing lumbar pain. Another cause is caused by long-term and accumulative lumbar trauma, such as some repairers who work in a sitting position for a long time and often operate in a non-physiological position, as well as bank and company employees who work in a fixed position for a long time. In addition, some workers who need to bend over and over again, such as usually do not pay attention to strengthen the exercise of the lumbar back muscle, can have accumulated injury of the waist, forming lumbar muscle strain. In addition to the above-mentioned reasons, some other factors should not be ignored, such as wind and cold, humidity, etc. Some patients sleep on a damp floor all year round, and some live in dark and damp basements. These factors can reduce the body’s resistance, make small blood vessels contract, muscle spasm, fascial exudation and adhesion, thus affecting the nutrition and metabolism of muscles, leading to muscle degeneration, which is clinically called lumbar myofasciitis, rheumatic myositis, etc. In fact, it is difficult to distinguish this kind of pain from lumbar strain injury, and clinical diagnosis and treatment are made according to The clinical diagnosis and management are made according to lumbar strain. Some patients often complain that some doctors diagnose me with lumbar strain, while others diagnose me with lumbar myofasciitis, but they are not sure what the disease is. In fact, these diagnoses are the same thing, and the clinical treatment is the same.
