If a lumbar disc herniation occurs in the lumbar spine, it will cause the lumbar disc to be removed from its original position, and surrounding nerve root edema, nerve root compression, and vertebral joint instability will occur. Because a lumbar disc herniation is mechanical and basically cannot be recovered by its own strength, serious treatment is required after a lumbar disc herniation. There are two methods of treatment: one is conservative treatment; the other is surgical treatment. Conservative treatment means rest, anti-inflammatory pain relief, elimination of local nerve root edema, after a long time the cone and the surrounding nerves can regain a new balance, so that the symptoms are gradually reduced, or even completely relieved, the lumbar spine function can remain largely normal. However, if multiple vertebrae bulge, it will seriously affect the biomechanical stability of the lumbar spine, which will cause weakness, pain, numbness and even severe pain in the lower limbs, and even cause paralysis of the lower limbs, which may require surgery, so lumbar disc herniation and lumbar misalignment cannot recover by themselves.
