Whether it is lumbar disc herniation or cervical spondylosis (cervical disc herniation), it is a very common orthopedic disease, which brings about neck and lumbar pain and numbness in the upper and lower limbs can seriously affect people’s life and work, and many people will become unable to sit and walk overnight, and even lying down can be painful. “I’m not doing anything, how come I have a herniated disc?” Many addicts will have this question. In fact, you don’t have to “do”, a long time in front of the computer or mahjong table sitting still, is a great danger to the intervertebral disc. First of all, sedentary will lead to increased internal pressure of the intervertebral disc. The intervertebral disc is like a small “bun” in the middle of the vertebral body to play the role of a buffer, “bun” filling called the nucleus pulposus, “bun” skin called the fibrous ring. There is pressure in the “bun”, and this pressure changes at any time with the body’s postural changes and movements. For example, when a person is lying down, the pressure in the “bag” is reduced to 30, and when the body is standing, the pressure in the “bag” will become 70, and when a person is sitting straight, the pressure of the disc will increase to 120, which is four times the lying position. If you sit with your back arched, this pressure will be even greater. It can be imagined that if you sit like this for more than ten hours a day, sometimes not even move, then the disc has to withstand the continuous pressure, undergo a long period of damage, “bun skin” local increasingly thin, one day, perhaps “bun skin child” will open the skin of the flesh The nucleus pulposus as the “filling” falls out and presses on the nerves behind, which is a herniated disc, causing pain and numbness in the upper or lower limbs, and even pressure on the nerves, dizziness and swelling, and urinary and fecal disorders. The poor nerve root compression will be edema and inflammation, which is why it causes severe pain in the acute phase, hitting the head against the wall, elbows and knees, staying up past dawn, and pain. Because the “skin of the bag” is broken, the “filling” is usually not returned, so the nucleus pulposus of the protruding disc is often not returned. Second, sedentary will lead to fatigue and softening of the lumbar muscles, making the loss of the protective effect on the lumbar spine. If sitting for a long time, the lack of lumbar back muscle exercise, coupled with improper sitting posture, or crooked, or twisted, will lead to lumbar muscle strain, scoliosis, muscle, ligament and joint capsule elasticity will become poor, thus making the stability of the lumbar spine joint is greatly challenged. When the lumbar spine is not protected by muscles and ligaments, the intervertebral discs are not protected by them and are more likely to suffer injury and protrude, and the small joints are more likely to be misaligned. In addition, muscle and other soft tissue strain can also lead to back pain, especially after a night’s sleep back pain is more obvious, feel better after activity. So when people have low back pain, do not be careless, it is likely that more serious problems will follow. It is clear that even if there is no trauma, no strenuous exercise, just “sitting”, you can still suffer from a herniated disc. Whether you are a working person, or a retiree, as long as you have the habit of forgetting to return to the hemp table, sedentary gaze, the lack of back exercise, there is damage to your body “bun”. In order to avoid the difficult disc herniation, I advise you to get up and move!
