There are three main cases of back pain after standing for a long time: strain injury, lumbar spondylolisthesis, and lumbar disc herniation. The specific situation is as follows: 1, strain injury: the most common clinical, often related to personal constitution, such as low back pain, is a certain probability of occurrence, and personal susceptibility to the body has a relationship. The same workload, stand the same time, some people have back pain, some people do not have back pain, because everyone’s muscles, ligaments, bones are not the same degree of toughness and tolerance, so even if there is pain, just may not adapt to long periods of standing, and will not be much of a problem. That is, when you need to have to sit and stand for a long time, wear a lumbar support. If there is already strain pain, you can put on plasters, pay attention to rest, that can get better; 2, lumbar spine slippage: if always stand for a long time on the occurrence of pain, you need to go to the hospital to take a film, to investigate whether there is a deep-seated cause. Because lumbar spine slippage is present in some people, and is also more common in the clinic. For example, some people are born with a piece of the lumbar spine that is broken and is in a state of slippage, so it is necessary to take a film to find out the problem and to treat it early; 3. Lumbar disc herniation: it must be detected by lumbar spine nuclear magnetic examination.
