Lumbar disc herniation is most common in young adults of working age, and in most cases, it is a chronic process from quantitative to qualitative changes. In daily work and life, improper body position or posture can cause the lumbar intervertebral discs to be repeatedly subjected to excessive compression, torsion, and other loads, resulting in tiny injuries to the discs. Long-term repeated cumulative damage can cause the lumbar disc damage is increasing, the nucleus pulposus of the intervertebral disc degeneration, and then in such as sneezing or laughing and other abdominal pressure suddenly increased action, or lumbar sudden force, lumbar sprain and other circumstances, can make the disc has been a small injury suddenly rupture out of the lumbar nerve root, compression, causing severe lumbar pain, and even appear to radiate to the side of the lower extremities of the pain and numbness and other serious symptoms, this is the lumbar intervertebral disk, and so on. This is the acute attack of lumbar disc herniation. After the lumbar disc herniation, although the symptoms can be relieved after conservative treatment, but the lumbar area can be aggravated again and again after sustained strain or slight trauma, so the condition is repeated leading to the patient’s pain and suffering, which can seriously affect the work and life, and the serious condition even requires surgical treatment. Therefore, it is very important to strengthen the protection of lumbar function and functional exercise for people who have already experienced lumbar pain or lumbar disc herniation episodes. Effective functional protection and exercise of the muscles of the lower back can help maintain lumbar stability and can effectively prevent acute and chronic lumbar injuries and low back pain, which is especially important for patients who have had acute and chronic lumbar muscle injuries or lumbar disc herniation and are currently in remission. Cold and humidity can stimulate muscle spasms and induce lumbar pain, and can induce or aggravate the symptoms of lumbar disc herniation, so attention should be paid to keeping the waist warm, and attention should be paid to avoiding colds and chills; when working in cold and humid conditions, attention should be paid to the waist’s rest and working posture, to prevent over-fatigue, to prevent the lumbar muscles from being sprained; sleep at night to pay attention to keeping the warmth, and sleep on a hard board bed. For surgical patients, lumbar disc removal surgery can only remove the nucleus pulposus which has been deformed and protruded or prolapsed, as well as part of the fibrotic nucleus pulposus in the annulus fibrosus. The residual nucleus pulposus after surgery may further degenerate and fibrotic, and may protrude along the foreign protruding position again under the action of external force; at the same time, due to the trauma of the surgery as well as the influence of other factors, the degeneration of the surgical section may accelerate, thus resulting in Joint protrusion hyperplasia, lumbar spine instability and other changes, all of which may lead to recurrent low back pain and lumbar disc herniation reoccurrence in patients. As long as we pay attention to the correct use of the lumbar region and careful maintenance, we can reduce lumbar strain, slow down the degeneration of the lumbar spine aging, and effectively prevent the occurrence of lumbar and leg pain symptoms.
