Lumbar sprain is a common injury in daily life, which can occur at any age, and it is so widespread and painful that you may have to go to the hospital for emergency treatment. So, what should I do if I have a lumbar sprain? How to prevent it? To answer these questions, we must first understand why lumbar sprains occur. The lumbar region includes the lumbar spine bones, ligaments, muscles, and fascia tissue. When the lumbar region is subjected to stress (heavy lifting, bending, getting up, etc.), the muscles and fascia of the lumbar region are strained, torn, and bleeding due to excessive or uneven stresses. The pain can be so severe that you cannot even stand or make any movements, and the severe pain can only be relieved after a long period of time. A lumbar sprain can occur in all aspects of daily life, sometimes simply by poor posture or by suddenly doing a certain action. So what should I do if I have a sprained back? Should I go to the hospital right away? We have learned that lumbar sprain is an acute injury to the musculofascial soft tissue, so the most important thing is to lie down as soon as possible after the sprain, so that the force on the musculofascial tissue is reduced, get rest, so that the pain will gradually reduce. In addition, the use of cold compresses, you can use a towel dipped in cool water, can also be used plastic bags wrapped in ice, put on the painful parts, can directly reduce pain, more important is to make capillary constriction, reduce the myofascial tissue bleeding. After 72 hours, change to hot compress, when the damaged capillaries have stopped bleeding, hot compress can promote the absorption of bruises and blood circulation, so that soft tissue repair as soon as possible. There is also a very important point is that for more serious sprains should be bed rest for at least 3-5 days, so that the muscles and soft tissues can get a better rest. The choice of bed harder better, but not necessarily a hard bed, this is due to the hard bed may cause pain in the process of bed rest protruding parts of the bone, or even injury. While resting in bed you can take oral pain relief and blood circulation drugs, or apply topical creams or emulsion-type drugs to help reduce pain. If there is only lumbar pain after the sprain, but no leg pain, numbness and weakness, and no urinary or fecal disorder, you can temporarily not worry about the herniated lumbar disc compressing the nerve, so you can go to the hospital without hurry, because even if you go to the hospital for emergency treatment, if it is okay to take ordinary X-rays (most of them are not skeletal problems), its treatment is the same way as above. If you are strictly bedridden for 3-5 days and there is no improvement (please note that “strictly bedridden” and “no improvement” are used here, if you are not strictly bedridden, or if there is some improvement but it is not healed, it does not count), then you should go to the hospital. The most important question is Another major concern is how to prevent lumbar sprains. We know from the causes of lumbar sprains that it is necessary to move heavy objects according to your strength and to master the correct posture. In daily life, lumbar activities should be gentle, do not make a strong effort, sports should also do the preparatory activities first. There is also a very important point is the daily functional exercise of the lumbar back muscles, such as Xiao Yan Fei and swimming, can make the lumbar back muscles stronger and more powerful, so the chance of sprain is greatly reduced.
