Stiffness and painful symptoms in the lower back after waking up in the morning may be caused by lumbar muscle strain. Patients with lumbar muscle strain will often sit for a long time, stand for a long time, work bent over for a long time, and work and study in a fixed posture for a long time. For too long, the lumbar muscles are under tension, putting the muscles at risk of injury. If the trigger is not eliminated, the injury will not be relieved and there is a possibility of gradual accumulation and the formation of old scarring. When sleeping, although the tension and stiffness of the muscle is relieved to a certain extent, but because of the existence of scar tissue, the blood circulation of the lumbar muscles will be affected, in the human body for a long time to maintain a state of immobility, the local blood circulation will become poor, but will appear after rest, sleep stiffness and pain symptoms of the lumbar region. It is best to treat this symptom in a timely manner, with topical and internal blood-strengthening drugs, local manual massage, acupuncture treatment, physical therapy and so on. Patients whose symptoms are not relieved after a week of treatment are best treated in hospital after diagnosis.
