Under what circumstances does back pain occur? In my treatment experience, even if I were to ask these two questions to a random sample of people on the street, I believe that most people would answer in the affirmative. This is because the condition of low back pain is indeed extremely common, especially in middle-aged and older people over 40 years old. What are the causes of low back pain? I’m afraid the most common ones are acute sprain of the lumbar muscle, lumbar muscle strain, dislocation of the small lumbar joints, bulging or herniated lumbar disc, lumbar myofasciitis, lumbar supraspinous or interspinous ligament injury, and other such diseases. Don’t look at the back can get so many kinds of diseases, but you should not worry too much, because except for more special or serious cases, the vast majority of these diseases can be prevented and self-treated by themselves (in the vast majority of cases, not necessary surgery). Below I will give you some knowledge of self-protection and treatment related to low back pain that is more easily grasped by the general public. Important basic principles: 1. To cure the disease, first of all, try to avoid the occurrence of low back pain, or to avoid or do less actions that can cause low back pain; only by removing the causative factors can we treat low back pain at its root, otherwise, I am afraid that the doctor can only become a god to cure you of your low back pain! 2, usually to strengthen the protection, that is, to strengthen the relevant muscles, especially the lumbar back muscle muscle strength exercises, in order to enhance the resistance of the waist to external loads or stimuli, which can also reduce the occurrence of low back pain. 3, when low back pain occurs must be appropriate and reasonable rest, especially lying down or prone, so that the damaged tissues get enough rest, the disease can be the fastest recovery. 4, never just find inexperienced masseurs and other massage massage with greater force, prone to pain aggravation or even aggravation of the condition, resulting in serious consequences. Under these principles, let’s introduce some basic prevention knowledge to you: 1. Prevention of back pain triggers: bending over to carry heavy objects, bending over for a long time to brush teeth or wash clothes, bending over for a long time to sit at work (such as computers) and so on. So from this point of prevention, we need to try to avoid these situations. (1) carrying heavy objects should first squat down, and then move up; (2) washing clothes, long hours of work, should often get up and move for a while, such as half an hour should have about 5 minutes of activity time; of course, sitting is also very important, do not do a good posture, the damage to the waist will certainly be more serious. And when we work long hours facing the computer, it is best to use the sitting posture in the following figure. 2, related muscle strength exercises: abdominal muscles and lumbar back muscles muscle strength exercises. Because these two groups of muscles are a pair of antagonistic muscles (that is, a group from the front to support our body, the other group from the back to support our body), both need to have enough strength to maintain our normal posture. Think about this in particular, these muscles have to work for us for about seventy to eighty years, do not exercise them stronger, and how can they serve us properly for so many years? If we can do all of these considerations above, you can basically ensure that your back can work properly for many years.
