The disease of lumbar intervertebral disc herniation is mostly found in sedentary people, such as people who often sit in the office, and drivers, when the onset of the disease will be particularly painful, the waist will appear serious discomfort, especially at night when the pain will increase, let us learn about the following knowledge. The lumbar disc herniation: is the central nerve and cauda equina nerve compression, causing lumbar and leg pain, walking and bending activities are limited, sitting and sleeping difficulties, and even urinary and fecal incontinence, some patients can cause lumbar spinal stenosis and paralysis, divided into bulging, protrusion, prolapse and other symptoms. Most patients have a history of lumbar trauma, chronic strain or cold and dampness before the onset of the disease, and are commonly found in the elderly or sedentary people. Pain characteristics of lumbar disc herniation: Lumbar disc herniation is the most common cause of low back pain, the light and heavy characteristics are: light during the day, heavy at night, light in the morning, heavy in the afternoon. It is heavy after exertion, light after rest, heavy after standing and walking and sitting, light after lying in bed. Coughing, stooling and bending are heavy, and resting is light. The attack is characterized by sudden onset, severe spasmodic pain, tolerable in mild cases, heavy pain like lightning, radiating pain of the lower limbs along the buttocks, often with leg pain heavier than low back pain in the later stages. The symptoms of lumbar disc herniation that are not known to the public: 1. sciatica This symptom of lumbar disc herniation is a discharge pain along the direction of sciatic nerve travel, radiating from the lower back to the buttocks and then to the lower limbs, dorsum of the foot or lateral foot, and may be accompanied by numbness. 2, lumbago The most common symptom of lumbar disc herniation, lumbago can be reduced after several days or weeks of rest, once labor or work lumbago is aggravated again, recurrent, the course of the disease for months or years. The lumbar disc herniation is widely present in all walks of life, and there is a large proportion of people who work in a sitting position for a long time. In recent years, the proportion of lumbar disc herniation among drivers, office workers and computer users has been on the rise. 3, cauda equina nerve compression The symptoms of this lumbar disc herniation are dullness of sensation in the bilateral legs, heel and perineum, and dysfunction of the bowels and urine. 4.Lateral lumbar herniation Restriction of lumbar activities, pressure pain at the lesion site and spasm of the canthic spine muscle, hyperalgesia, abnormal reflexes and decreased muscle strength in the lower limbs. 5.Leg elevation test and strengthening test A patient with lumbar disc herniation is lying down, and passive straight leg elevation of the lower limb causes obvious lumbar pain and sciatica due to the strain on the sciatic nerve, which is a positive straight leg elevation test. The strengthening test is a positive test if the pain is aggravated by strong dorsiflexion of the pedal joint, which is a method to check for radicular tension due to nerve root compression. The vast majority of patients with lumbar disc herniation have a positive test for these two tests. 6, cold sensation in the limbs A few cases (about 5% to 10%) feel cold and chilly in the limbs, mainly due to the stimulation of sympathetic nerve fibers in the spinal canal. This is also a symptom of lumbar disc herniation. These symptoms of lumbar disc herniation must be treated with caution. After the symptoms of lumbar disc herniation are discovered, you must be calm and not panic, and patients should go to a regular hospital for diagnosis and treatment as soon as possible to avoid the disease from endangering your health. The reason for suffering from lumbar disc herniation: lumbar disc herniation is a relatively common orthopedic disease, suffering from lumbar disc herniation after the nucleus pulposus protrudes from the annulus fibrosus leading to compression of nerves, which will cause patients to produce back pain, leg pain, lower limb radioactive pain, numbness, limited activity and so on, seriously affecting the normal life of patients. The lumbar intervertebral disc herniation is a syndrome caused by the degeneration of the pushing disc, the rupture of the fibrous ring, the protrusion of the nucleus pulposus stimulating or compressing the nerve root and cauda equina nerve, is one of the common clinical lumbar disorders, the incidence of 15.2% in the population. The pathogenic factors are roughly divided into the following: 1, degenerative changes in the lumbar intervertebral discs The main cause is long-term chronic cumulative strain injury. Commonly over 30 years of age, degeneration of the lumbar intervertebral disc fiber degeneration, elasticity, thinning, brittle, nucleus pulposus dehydration, tension decreased, on this basis, in the presence of a certain external force or disc pressure suddenly increased, can make the fiber ring rupture, the nucleus pulposus protrusion. 2, lumbar trauma About 10% of patients have a history of various degrees of trauma. Common forms of trauma include moving things, lifting heavy objects, various forms of lumbar sprains, falls, etc. All these traumas can cause the disc to rupture and the nucleus pulposus to protrude from the ruptured part when the pressure tension on the nucleus pulposus exceeds the stress on the annulus fibrosus in an instant. 3, sudden increase in pressure within the lumbar intervertebral disc Patients do not have an obvious history of trauma, but are only caused by violent coughing, sneezing, constipation, and forceful breath-holding. 4, environmental factors People who work or live in a humid and cold environment for a long time are more likely to suffer from lumbar disc herniation. Because cold or damp can cause small blood vessel contraction, lumbar muscle reflex spasm, so that the pressure of the intervertebral disc increased, and cause the fiber ring rupture. According to statistics, people who work underground in mines for many years have a higher percentage of this disease. 5, improper lumbar posture whether during sleep or in daily life, work, when the waist in a flexed position, such as a sudden rotation, it is easy to induce a herniated nucleus pulposus. In fact, in this position, the pressure in the intervertebral space is also higher, which can easily cause the nucleus pulposus to protrude to the rear. 6, sudden weight-bearing Sudden increase in lumbar load without adequate preparation may not only cause lumbar sprain, but also easily cause herniation of the nucleus pulposus. 7, occupational factors This disease is common and multi-infarct, widely present in all walks of life, but still common in industries with high labor intensity. In addition, a large proportion of people who work in a sitting position for a long time also suffer from the disease. In recent years, the proportion of drivers, office workers, computer workers, etc. who suffer from lumbar disc herniation has been on the rise. 8, age The disease occurs in people aged 25-50, accounting for more than 75% of the overall incidence. 9, gender aspect lumbar disc herniation is mostly seen in men. 10, other aspects The relationship between lumbar disc herniation and genetic factors has not yet been postulated, but it is certain that certain people with congenital dysplasia of the lumbar spine, such as Si scoliosis, congenital spina bifida and other diseases, also have a higher chance of complicating lumbar disc herniation. In addition, such as women during pregnancy, due to special physiological reasons, resulting in sudden weight gain, coupled with relative muscle weakness and ligamentous laxity, is also a dangerous period to induce this disease. How to prevent the occurrence of lumbar disc herniation? 1, strengthen the exercise of the lumbar back muscle Increase the physical exercise of the lumbar back can strengthen the strength of the lumbar back muscle and protect the lumbar spine. When lifting heavy objects should squat, body forward, using the muscles of the legs to force. Lack of exercise in the elderly should pay particular attention to this point. Exercise bending should be moderate, the amplitude should not be too large, to avoid injury to the lumbar spine. 2, maintain the correct standing, sitting posture wrong standing, sitting posture so that the spine is not normal bending, resulting in uneven force on the lumbar intervertebral discs, lumbar muscle strain, laying hidden dangers to the lumbar spine health. Sitting in a chair with a backrest, should try to backward so that the waist back against the back of the chair, the need for long-term operation of the computer people do not stilt, to reduce lumbar fatigue. 3, a healthy balance of diet to maintain a balance of nutritional intake, you can pay attention to more food containing protein, calcium, vitamins and other substances. 4, to ensure sleep quality sleep should relax the waist, fully relieve the pressure in the lumbar intervertebral disc, promote the lumbar intervertebral disc nucleus pulposus, fibers to fully absorb nutrients, delaying the decline. Ensure the quality of sleep. Extreme relaxation of the waist, so that the pressure within the lumbar intervertebral disc in high-quality sleep is fully released, so that the nucleus pulposus, fiber ring to get better nutrition, delay the onset of degeneration, and thus prevent lumbar disc herniation. 5, do a good job in advance to prevent cold warmth in the autumn and winter season, the temperature changes more frequently, to do a good job in advance to prepare for cold warmth, especially to do a good job of neck, waist, back warmth, to prevent the occurrence of lumbar disc herniation. In addition to this, keeping warm in autumn and winter can also prevent colds, coughing and sneezing will occur in autumn and winter. When sneezing and coughing, the increase in abdominal pressure can easily increase the pressure within the lumbar disc, strain the back muscles, and then occur lumbar disc herniation. Thus, increasing clothing at the right time and preventing colds are also important situations to prevent lumbar disc herniation from occurring. In addition to active treatment, patients with lumbar disc herniation should also pay attention to daily health care, such as quitting smoking and drinking; eating more nutrients that enhance bone strength and muscle strength; and also trying traditional medicine health care such as hot compresses, massage, and herbal fumigation.
