Lumbar muscle strain is one of the common disorders in chronic low back pain, mainly due to aseptic inflammation localized in the lumbar muscles. Aseptic inflammation is caused by chronic injury to the ligaments, fascia, muscles and other soft tissues of the lumbosacral region. As a result, diffuse pain may appear on one or both sides of the lumbar and hip regions, with recurrent hidden pain in the lumbar region, aggravated by exertion and relieved by rest as the main manifestation. Aseptic inflammation is an inflammatory reaction caused by physical and chemical factors. When aseptic inflammation occurs in the human body, the site of inflammation is not infected by bacteria or other pathogens, so there is no need to give antibiotics and other drugs. When lumbar muscle strain occurs, it is important to pay attention to conditioning in daily life.
