1.Lumbar intervertebral disc herniation: compression of nerves, resulting in lumbago, low back pain, walking restrictions, intermittent claudication and so on. 2.Lumbar intervertebral discogenic low back pain: that is, the disc herniation is not obvious, but the low back pain is obvious, recurrent, conservative treatment is ineffective. At this time, the intervertebral disc has already appeared structural damage, thus causing pain. 3, lumbar intervertebral foraminal stenosis: middle-aged and elderly patients with low back pain, intervertebral foraminal bone spurs or ligament hypertrophy and other reasons, the formation of intervertebral foraminal stenosis, resulting in nerve channel obstruction. Expanding the intervertebral foramen can do nerve decompression. In short, the lumbar disc herniation symptoms are more serious, frequent attacks, conservative treatment is ineffective, seriously affecting the work life and learning and other people, it is recommended to use curved blade needle, silver needle, needle knife, etc. to perform extra-vertebral soft tissue laxation to eliminate the cause of the disease.
