The term “lumbar disc herniation” refers to a series of changes in the lumbar intervertebral discs due to degenerative changes, rupture of the annulus fibrosus, and herniation of the nucleus pulposus. If the protruding nucleus pulposus compresses the nerve root, cauda equina, or produces inflammatory stimulation, and manifests a series of clinical signs and symptoms, it is called “lumbar disc herniation”, commonly known as “lumbar herniation”. The term “lumbar disc herniation” refers to the state of herniated nucleus pulposus, and “lumbar disc herniation” refers to a series of painful symptoms caused by the herniated nucleus pulposus as the main manifestation of the disease. “Lumbar disc herniation is a common clinical disease and the main cause of back and leg pain, which often brings a lot of pain to the patient’s life and work, and even causes disability and loss of labor ability. Clinical symptoms mainly include lumbar pain, radiating pain in unilateral lower limbs, intermittent claudication, restricted spinal movement, and numbness. Lumbar disc herniation is the main cause of low back pain and is one of the common disorders in the pain department. “Lumbar disc herniation” is caused by “lumbar disc herniation”, but not all “lumbar disc herniation” will necessarily lead to lower back and lower extremity pain. Studies have shown that herniated discs are very common (herniated discs are often found in the lumbar and cervical spine), and that asymptomatic herniated discs occur in about 1/3 of the normal population. In other words, if three normal people stand together, one of them may have a herniated disc in the lumbar or cervical spine. The pain occurs mainly due to the protrusion, degeneration of the nucleus pulposus on the neighboring tissues (mainly for the sinus nerve and spinal nerve root) of the stimulation and compression, at the same time, the nucleus pulposus glycoproteins and other biological substances overflow, the release of histamine and so on, causing local chemical inflammation, resulting in chemical and mechanical radiculitis caused by the cause of chronic low back and leg pain, either mild or severe. And the degeneration of the lumbar spine also tends to occur at the same time in other tissues of the lumbar region, such as the small lumbar intervertebral joints, ligaments, lumbar muscles, etc., resulting in localized chronic inflammation of these tissues, causing pain. The two factors interact and aggravate each other, resulting in progressive development of low back pain. According to the relationship between the herniated degree of the intervertebral disc and the annulus fibrosus, it is clinically divided into: bulging disc, herniated disc and prolapsed disc. With the continuous development of science and technology, we have achieved a further understanding of the disease, and developed a series of more effective means of treatment. For example, mild cases can receive: medication, physical therapy, acupuncture, massage and so on. For severe cases, surgery, transforaminal lumbar disc removal, radiofrequency coagulation of the nucleus pulposus, and low-temperature plasma radiofrequency ablation are acceptable. For patients who have failed conservative treatment and cannot meet the criteria for surgery, “nerve block” treatment is also a very good choice. Nerve block is a kind of therapy in which analgesic and anti-inflammatory drugs are injected directly into the vicinity of the diseased nerve root, which is safe and effective and effectively fills the treatment gap between drug treatment and surgery.
