Lumbar disc herniation is one of the more common lumbar disorders in clinical practice, mainly affecting manual laborers, drivers and sedentary office workers. The degenerative changes of the lumbar intervertebral discs themselves are the most basic factors in its development. After adulthood, the lumbar disc gradually lacks blood supply and has poor repair ability. Under some triggering factors that can lead to a sudden increase in pressure on the disc, the less elastic nucleus pulposus may pass through the weak fibrous ring, causing the nucleus pulposus to protrude and compress the lumbar nerve, causing pain and numbness. Common precipitating factors include increased abdominal pressure, improper lumbar posture, sudden weight bearing, pregnancy, cold and dampness, etc. Clinically, the symptoms are mainly lumbar pain. Most patients have lumbar pain accompanied by pain and numbness in the hip and one lower limb, walking with a limp, difficulty bending over, and limited lumbar movement. Due to the lumbar pain, most patients stand in a protective posture position with the lumbar vertebrae laterally convex to one side. Local pressure pain in the lumbar region is obvious and the muscles are tense. Severe cases of lumbar disc herniation may manifest symptoms such as obstruction of bowel movement and urination, abnormal perineum and perianal sensation, and even incontinence and incomplete paralysis of both lower limbs. Patients with lumbar disc herniation should ensure absolute bed rest for about 2 weeks. This can be combined with symptomatic treatment with oral non-steroidal anti-inflammatory drugs for pain. Treatment is mainly conservative treatment and surgical treatment. Conservative treatment mainly includes traction, massage, physiotherapy and acupuncture, cupping and so on. Generally, if conservative treatment is ineffective or the lumbar disc herniation is serious, surgery can be considered. The prognosis of lumbar disc herniation is generally good. Usually the bed should not be too soft, try to sleep on a hard bed to rest. To have good sitting posture, avoid sitting and standing for a long time. Leave the bench after an hour of work and get up and move your lumbar spine. Patients with low back pain should also strengthen the functional training of the lumbar back muscles to increase the stability of the crest. If you need to bend over to get something, it is best to use hip flexion and knee flexion squatting to reduce the pressure on the back of the lumbar disc. In short, herniated lumbar discs are valuable for prevention, and the lumbar region should not get cold.
