To understand how lumbosacral pain occurs first we need to know where the lumbosacral region is located and the role it plays. The lumbosacral region It is the hub of the trunk where the upper body is connected to the lower body and has more structures. The muscle strength of the lumbosacral region provides us with the ability to stand, walk and lift heavy objects. There are many ligaments between each lumbar vertebra to maintain their stability, from which it can be seen that when we lack sufficient training or do not have strong muscle strength, too much strain, once there is a sudden exertion, the movement may damage the ligaments and muscles, thus occurring lumbosacral pain and weakness, according to statistics 80% of adults have experienced significant lumbosacral pain in their lifetime. The common causes can be summarized into four major categories: 1, caused by disorders of the spinal bones and joints and their surrounding soft tissues. Such as exertional lumbago, acute and chronic lumbar injuries, osteophytes, arthritis, lumbar muscle strain, local injuries, bleeding, edema, adhesions and muscle spasms, etc. 2. Caused by spinal cord and spinal nerve disorders. Such as spinal cord tumor, myelitis, lumbar disc herniation, etc. caused by low back pain. 3. Caused by diseases of internal organs. Such as kidney disease, infection of the uterus and its adnexa, tumor can cause lumbosacral pain, and such patients are often accompanied by the corresponding specialist symptoms. 4.Caused by psychosomatic factors. For example, patients with hysteria may also have lumbar disease as the main complaint, but there are no objective physical signs. Prevention: 1, appropriate exercise can maintain muscle strength and flexibility. For example, jogging, walking backwards, swimming. 2, use the correct method of lifting or carrying heavy objects, especially when carrying too heavy and too large objects to do a good hair posture. 3 both standing and sitting to maintain a proper posture, rather than a very lazy body posture. Do not sit and stand for a long time to maintain a fixed posture, maintain a posture once more than 20 minutes, the muscles will begin to tighten, no matter what posture, maintain too long is not good, . Do not wear shoes with heels, any shoes with heels will aggravate back pain. 4, try to lie flat when sleeping and resting, less side lying, which is conducive to relaxing the muscles of the back, choose a hard bed with a thick mattress than a soft mattress is more conducive to your back pain relief. 5, maintain the appropriate weight, excessive weight will put too much pressure on the spine and low back muscles to accelerate the strain on the muscles and joints. 6.Avoid smoking.
