Xiao Zhang is 28 years old and sits in front of the computer all day at work. Recently, he always felt pain in his shoulder. At first, Zhang did not pay much attention to, did not expect to get heavier and heavier, and finally hitting the keyboard also became a problem. He had no choice but to go to the hospital to see a doctor. After the doctor asked him in detail about his condition, he was advised to do an MRI of the cervical spine. The test results confirmed that Zhang had a cervical disc herniation. His shoulder pain was caused by a problem in his cervical spine. Human pain signals are transmitted by nerves, if there are no nerves there will be no pain, and only if there is an abnormality in the nerves and there is a problem in the transmission of signals will there be pain. The human spine is like a candy cane, with individual vertebrae connected by fibers and ligaments, except that in the middle of the spine is the spinal cord, not a bamboo stick. The human nerves emanate from the spinal cord, pass between the two vertebrae, and then accompany the blood vessels and muscles all the way to the human skin and other places. If something goes wrong with these nerves or if they are stimulated in an abnormal way, pain will occur. Most of the pain in the shoulder is due to problems with the nerves in the neck, and most of the problems occur where the nerves pass out from between the vertebrae. The doctor asked Zhang to do an MRI to see the situation of the nerves in the neck, to see if they are being squeezed or other harmful stimuli, and then to give different treatments according to the stimuli received. Learning to use a computer was once a dream come true for many people, but long-term computer exposure is the cause of cervical spondylosis in many young people. The elderly suffer from cervical spondylosis is a reflection of the aging process, while young people suffer from cervical spondylosis “culprit” is mostly their own bad habits, the main is to maintain the wrong posture for a long time, coupled with the lack of appropriate exercise. Long-term low or twisted neck reading, or long-term stare at the display screen so that the neck in a posture, will cause an imbalance of pressure between the two vertebrae, or excessive stretching of the neck muscles inflammation. These can cause local nerve stimulation, causing pain and other symptoms in the corresponding area. Our ancestors had a saying “sit like a bell, stand like a pine”, which teaches us how to sit and stand, and this saying is very reasonable. Because if you do “sit like a bell, stand like a pine”, your spine will be in a balanced position, so as not to stimulate or compress the nerves, and will not appear the corresponding disease. Another point is to pay attention to rest, work long hours don’t forget to stand up and move, stretch your waist, move your cervical spine, give yourself a chance to relax, I believe it will help your health.
