Recently there are often patients with a CT or MRI to ask: doctor, look at my report card how to write the disc has a “herniation”, “bulge”, in the end this is what happened? This time, check the patient, no back pain, no leg pain, the lumbar spine feels a little tired, the lumbar spine activities forward flexion and back extension left and right flexion without any problems, this time tell him, this is not to worry, this is a lumbar disc herniation, not lumbar disc herniation. At this time the patient is dizzy, what is the difference between the two? Here I will explain the difference between the two. The most typical symptom is radiating pain below the calf, that is, a line of pain radiating below the calf, numbness, etc. If such a symptom occurs, it means that there is a possibility that the lumbar disc is compressing the nerve root. If such symptoms occur, it means that the lumbar disc may be compressing the nerve roots, and there is also a situation when there is numbness around the anus and obstruction to urination and defecation, which means that the protrusion may be too large to compress the cauda equina nerve at the back, which requires emergency surgery. Only when these symptoms occur can it become a lumbar disc herniation and the lumbar disc herniation needs to be treated. A herniated lumbar disc is, according to epidemiological statistics, present in about 50% of people over the age of 50, and there are far fewer patients with a herniated lumbar disc, so there is no need to worry unduly. At this point, someone else may ask: Will my herniated lumbar disc develop further into a lumbar disc herniation then? My answer is: there is this possibility, because lumbar disc herniation is often caused by uneven force around the lumbar disc, why there is uneven force, often because we are now in a long-term “pimp” posture “pimp” posture will The loss of the forward curve of our lumbar vertebrae leads to uneven force on the lumbar discs, resulting in protrusion, which is further aggravated by trauma, such as after twisting the waist, will lead to further aggravation of the protrusion, which may compress the nerves and produce lumbar disc herniation, so restoring the curvature of the lumbar vertebrae and returning the lumbar discs to an evenly stressed state is the best way to prevent lumbar disc herniation. The following is a simple combination of dynamic and static methods to restore the lumbar spine to its natural state. Still: when sitting in a chair, take a towel rolled into a towel roll, pad to the back of the lumbar spine, so that the lumbar spine to form a forward curvature. Move: stand straight after sitting, try to stretch the lumbar vertebrae backwards, so that the lumbar vertebrae form a state of extreme posterior extension, which is able to restore the maximum lumbar curvature.
