I've had a lumbar disc herniation for two years. Recently, there is a place where meat jumps on my ass. What happened?

The local displacement of the protruding intervertebral disc tissue exceeds the intervertebral space. The displaced intervertebral disc tissue is still connected with the original intervertebral disc tissue, and the diameter of the basal continuous part is larger than that of the displaced intervertebral disc part beyond the intervertebral space. Medical drugs usually include Hesheng Tang Sect, Hesheng Tang Wei and so on. Lumbar intervertebral disc is equivalent to a micro-motion joint, which consists of hyaline cartilage plate, fibrous ring and nucleus pulposus, and is distributed between lumbar vertebrae. Because of the degeneration or trauma of lumbar intervertebral disc, the annulus fibrosus breaks, and the nucleus pulposus comes out from the break, which compresses the lumbar nerve and causes radiation pain in the waist and legs. The medical profession believes that lumbar disc herniation belongs to the category of "low back pain and joint pain". The following six questions remind patients with lumbar spondylosis to pay special attention: 1, sleep on a hard bed. Sleeping on a hard bed can relieve the pressure on the intervertebral disc. 2. Keep good living habits, keep your waist warm and try not to catch a cold. Avoid catching cold and eating cold things, and don't stay in the air conditioner for a long time, which is not good for your waist! Strengthen the protection of the back. 3. Don't bend over hard (such as mopping the floor ……). Pay attention to labor posture, avoid bending over for a long time and excessive load, so as not to accelerate intervertebral disc lesions. 4. Don't bend excessively during exercise, otherwise it will not only fail to achieve the expected purpose, but also cause disc herniation. 5. Try to stay in bed during the acute attack and after the pain period is relieved. Pay attention to proper rest and don't be too tired, so as not to aggravate the pain. 6, in the usual diet, eat more foods with high calcium content, such as milk, dairy products, shrimp skin, kelp, sesame sauce, soy products are also rich in calcium, often eat, but also conducive to calcium supplementation, pay attention to nutritional structure. Prevention of lumbar disc herniation should start from school, family, work and pre-job training, so that every staff member can understand normal spinal physiology, correct labor posture, pay attention to labor protection, and avoid accelerating lumbar disc degeneration and injuries based on lumbar disc degeneration. Preventive measures should be taken from the following aspects: ① Regular health examination for teenagers or staff, and extensive publicity and education on prevention of lumbar disc herniation. (2) The labor department should stipulate the maximum workload of labor, so as to avoid spinal overload from promoting and accelerating degeneration. ③ Correct working posture, combining work and rest. ④ Strengthening muscles to exercise strong back muscles and balance the strength of spine can prevent back soft tissue injury and reduce the occurrence of lumbar disc herniation. Thank you for giving points.
