What is the reason for frequent leg pain?

I feel pain in my leg. Check that there are more and more middle-aged people with bad waist and legs. I have met many such people in clinic. Mr. Wang, 45, was on a business trip and took the train a few days ago. He slept on a hard sleeper all night. My back aches and my legs hurt when I get up in the morning, and I can't move at all. With a little movement, the pain extends from the hip along the lateral thigh to the calf and ankle joint, accompanied by weakness and numbness of the calf and foot. Someone told him "this is sciatica", while another fellow elder said "there may be something wrong with his back". Sure enough, when he went to the hospital for a check-up, Mr. Wang got lumbar disc herniation. The so-called lumbar disc herniation is due to the degeneration of various parts of the lumbar disc, especially the nucleus pulposus. Under the action of external factors, the annulus fibrosus of intervertebral disc ruptures, and the nucleus pulposus protrudes backward or into the spinal canal, which leads to the stimulation or oppression of adjacent tissues, such as spinal nerve roots and spinal cord, resulting in low back pain. And produce a series of clinical symptoms such as numbness and pain in lower limbs. Sciatic nerve is the largest peripheral nerve in the whole body, which is composed of some lumbar nerves and sacral nerves that meet in the pelvic cavity. When the spinal nerve roots and spinal cord at the corresponding stage are stimulated or compressed, the symptoms of sciatica will appear. About 98% of patients with lumbar disc herniation have leg pain, and the location and nature of pain vary with the location of disc herniation. Lumbar disc herniation caused by occupational factors used to be a common disease of the elderly, but with the development of society, more and more middle-aged people have this disease. Professionally speaking, lumbar disc herniation is more common in industrial workers with greater labor intensity. Nowadays, desk workers and salespeople, textile workers, students, drivers and editors who often stand are more common. Their posture is fixed for a long time, their posture changes little, and their waist muscles are often in a state of tension in a certain direction, which can cause lumbar disc herniation. In addition, people who are too obese or too thin are prone to lumbar disc herniation. People with obese abdomen have more adipose tissue and less muscle tissue, and the increase of abdominal weight will also increase the waist load, thus increasing the chance of lumbar disc herniation. However, people who are too thin have too little muscle tissue and weak strength, which easily leads to lumbar disc herniation. Correcting posture is very important. The best way to treat lumbar disc herniation is to stay in bed absolutely, but it is difficult to cure it radically. Standing posture: The correct standing posture should be eye-level, chin miniature, chest erect, waist straight, calf miniature, legs upright, and the distance between feet is about the same as the width of pelvis. In this way, the whole pelvis will lean forward, so that the gravity of the whole body will be evenly transferred from the spine and pelvis to the lower limbs, and then from the lower limbs to the feet. At this time, the gravity line of human body just passes through the back of lumbar vertebra or intervertebral disc, which can effectively prevent the nucleus pulposus from protruding. Standing time should not be too long, and proper activities should be carried out, especially waist and back activities, to relieve muscle fatigue in the back. Sitting posture: The correct sitting posture is that the upper body is straight, the abdomen is in, the jaw is slightly retracted, and the lower limbs are close together. If possible, it is best to put a footstool or footstool under your feet, so that the knee joint is slightly higher than the hip. If you are sitting in a chair with a backrest, you should try to keep your back close to the back of the chair on the basis of the above posture, so that the muscles of the lumbosacral region will not be too tired. Sleeping position: The better sleeping positions should be supine position and lateral position. When lying on your back, put a soft pillow under your lower limbs, so that your hips and knees can flex slightly, relax your muscles, reduce the pressure on the intervertebral disc, and reduce the tendency of intervertebral disc kyphosis. This sleeping position is the best sleeping position for patients with lumbar disc herniation. In addition, when choosing a bed, try to choose a slightly harder bed. A soft bed like Simmons can hardly make the muscles of all parts of the body have a full rest. Some middle-aged people who sleep in Simmons always feel backache and leg pain in the morning, which is probably the reason. There is also the need to strengthen physical fitness, especially the functional training of back muscles. Proper exercise can improve muscle blood circulation, promote metabolism, and achieve good therapeutic and preventive effects.
