★ Causes and prevention of lumbar muscle strain is a common disease. Many people have low back pain or have had low back pain. There is one of the most common low back pain. The pain around lumbosacral joints is about the size of the palm of your hand, or it is dull or painful, which is relieved when you get up in the morning and aggravated after exercise. It's hard to sit and stand for a long time. When I went to the hospital for examination, X-rays and blood tests were mostly normal. Although most patients with low back pain can live a normal life and stick to their work, over time, it will affect work efficiency and reduce the interest in life. This kind of low back pain is often called kidney deficiency low back pain in traditional Chinese medicine, that is, low back pain caused by lumbar muscle strain. Why does lumbar muscle strain cause low back pain? The waist is the midpoint of the human body. Lumbosacral joint is the only big joint in the human body that bears the gravity of the body, and it is the hub of waist activity. Prone leaning, backward leaning, left and right bending and rotation are all involved. No matter exercise or activity, the joint here bears more force than any joint in the whole body. When labor intensity is high or activity is high, there will be more joint activities. All joint activities involve muscles, so the muscles here are prone to fatigue and injury. Lumbar muscle strain refers to the decomposition of lumbar muscle due to overwork. Some people have little physical activity and labor intensity, but because of the wrong posture, the spine is in a semi-bent state, and the back muscles are always tense, which will cause strain over time, further develop into aseptic inflammation, stimulate nerve endings and cause pain, so low back pain occurs. It can prevent lumbago caused by lumbar muscle strain. How to prevent it? First of all, we should strengthen exercise and improve our physical fitness. Especially those who have been sitting for many years, their back muscles are weak and easy to get hurt. Therefore, it is necessary to strengthen the exercise of back muscles, such as doing some flexion, extension, left and right waist bending, gyration, supine, sit-ups, so that the waist muscles are strong, the ligaments are strong, the joints are flexible, and the chances of getting sick are reduced. Obese people should lose weight and reduce the burden on the waist. Secondly, we should pay attention to self-regulation, combine work and rest, and avoid an action that is fixed for a long time and forced to bend over. If we stand for a long time, we can squat. Squatting can not only relax waist and leg muscles, but also reduce physical exertion. Then pay attention to all kinds of postures in life. For example, when picking up heavy objects from the ground, kneel down to avoid bending over to increase the burden. When carrying heavy objects, keep your body as close as possible to the object, make it close to your abdomen, and squat your legs slightly; When you hold things high, you should not be forced to reach them; Keep your spine bent when you sleep. It is also important to avoid humidity and cold. Bao Jianguo
