Low back pain is the most common topic in daily life, with literature reporting that more than 65% of people have had low back pain troubles in their own lifetime, and some data suggesting that low back pain is the second most common type of cause of worker rest due to illness, second only to upper respiratory infections. Despite the high incidence, low back pain does not get much attention, so today we will talk to you about this unavoidable topic. The spine is the central axis of the body to play a supporting and protective role, it has four bends, respectively, by the vertebral body and intervertebral discs together, its surrounding also wrapped around and connected to the muscles, tendons and walking spinal nerves, in the usual activities, such a structure can play a cushioning shock, stabilize the body and increase the role of mobility. However, as we age, the spinal discs gradually lose water, the elasticity of the intervertebral discs gradually decreases, and the height gradually decreases, so the ligaments and muscles between the vertebrae appear relatively long, and then the adjacent vertebrae will be displaced when the body is bent forward or backward, that is, the vertebral instability in the mouth of the doctor, the surrounding muscles in this case in order to stabilize the spine will be vigorously and continuously contracted, and slowly fatigue. Slowly fatigue, there is also muscle strain, the beginning of more rest can slowly relieve the muscle edema, in the spine above the attachment of the place is stretched and bleeding, resulting in slow calcification, there is a common bone spurs on the X-ray, the body is trying to re-establish a stable spine, so the bone spurs grow larger and larger, finally the adjacent vertebrae connected together, the problem of spinal instability The spinal instability is repaired, but the excessive bone spurs squeeze the surrounding structures, especially the posterior nerves, and if it occurs in the lumbar spine this shows an inability to walk long distances, numbness and coldness in the lower extremities, etc. If it occurs in the neck, there is numbness in the hands, poor dexterity, and walking like stepping on cotton. This gives rise to lumbar spondylosis and cervical spondylosis, which are common in clinical practice. In other cases, trauma or car accidents cause the intervertebral disc fibers to break down and the nucleus pulposus protrudes and presses on the nerve roots at the back, resulting in sciatica, as it is known to the general public, and the pain usually follows the nerve path to the innervated lower extremities. It is often described clinically as radiating pain with numbness of the skin in the corresponding area. Other low back pain is caused by other diseases, such as: ankylosing spondylitis – this pain is more common in the morning after rest, with stiffness of the lumbar spine, and often occurs in adolescent males; vertebral tumors – most commonly seen in the elderly, with a history of tumors. The pain is mainly persistent and obvious at night when resting; spinal tuberculosis – usually common in the lumbar spine, usually a mild pain, the symptoms are reduced after rest and aggravated after exertion, often with low fever, fatigue, emaciation, night sweats, some patients also have pain in the root of the thigh, etc. In modern society, life is fast-paced, work pressure, many people long-term ambulatory or sedentary, but also always look at the cell phone of the low-headed people, over time, the spine appears to age before the old, outpatient clinics often see the 80s, or even 90s because of neck pain or low back pain to the clinic, an examination found that the physiological curvature of the spine has disappeared, the local osteophytes are obvious, only look at the X-ray may be considered a manifestation of the elderly, therefore Must pay attention in daily life, pay attention to healthy habits, reasonable physical exercise, so that their spine is always young.
