Many people with back and leg pain suspect that they have a herniated lumbar disc. Through Baidu or WeChat we will also learn some common sense: the spine will gradually degenerate as people get older, and a herniated lumbar disc compresses the nerves and causes back and leg pain. However, the vast majority of people do not know that the main cause of lumbar disc herniation is: excessive pressure within the lumbar intervertebral disc. The posterior side of the disc is relatively thin, and the strength of the fibers in the posterior part of the fibrous ring has been determined to be less than 100kp/cm? Long-term excessive internal pressure in the intervertebral disc can easily lead to rupture of the annulus fibrosus and induce the appearance of lumbar disc herniation. As shown above, these people are most likely to have lumbar disc herniation. At the same time: improper sitting posture, increased abdominal pressure, sudden weight bearing, pregnancy, cold and moisture are common factors that lead to increased internal pressure in the intervertebral disc and induce lumbar herniation. Prevention of lumbar disc herniation starts with correct posture: In addition, the knee is slightly finished when sneezing can share the abdominal pressure and the pressure on the spine. One-minute self-test of your lumbar spine: ① pain on one side of the lumbar region, radiating through the buttocks to the back of the thighs, up to the calves and feet, and sometimes a numbness, aggravated by coughing. ②After an acute lumbar sprain (i.e., flashback), the phenomenon of walking with a limp occurs. ③When sleeping flat on the back, the back pain cannot be straight and needs to be held by hand or pillow, or sleep on the side. ④The pain in the lower back is sore and cannot be relieved by sitting down and resting, and can be relieved by resting on the side. ⑤ A point 1 cross finger to the left and right of the spine in the lower back, with significant pain when pressed. ⑥positive straight leg raise test: the person being tested lies flat, extends the knee, and the other person raises the leg. A patient with lumbar disc herniation can have pain in the lower back and buttocks when raised within 60°, which is called a positive straight leg raise test. If you have any one of the above 6 symptoms, it is recommended to go to the hospital for examination, and the degree of lumbar degeneration can be checked by CT.
