There is a public perception that once a fracture is broken, even if the bone grows back, it will still leave “sequelae” and whenever it rains or gets cold, the old injury will “flare up” with pain. Is there any scientific truth to this statement? This is true, but it is not impossible to solve. So, what causes the pain to come back even after the fracture is healed? What can be done to solve this pain problem? Why does the “after” pain occur? A fracture is a serious traumatic condition that occurs in a fraction of a millisecond. The disruption of the continuity of the bone leads to abnormal bone movement; this, combined with the implosion-like process, leads to considerable damage to the soft tissues, eventually causing pain. According to TCM theory, “the owner of man, blood and qi ears.” A fracture is a disease that injures the tendons and bones, and the tendons and bones are disordered, the flow of qi and blood is obstructed, and qi and blood are stagnant for pain. Therefore, the fracture will produce pain. After the fracture is healed, although the fracture has grown well, it often happens that after several months or years, every rainy day, after getting cold, or seasonal change, the pain of the original fracture site appears, repeatedly. In folklore, people call this “the root of the disease”. How did the “root of the disease” fall? This is the relationship between blood stagnation and qi stagnation, and the mutual root of qi and blood, which is the cause and effect of each other. Why do the “root of the disease” often occur? This is because the stagnation of qi and blood stasis makes the tendons and veins unstable, and they are deprived of glory and nourishment, so that the tendons and qi are extremely weak and easily attacked by wind, cold and dampness. This is the reason why the fracture site has grown well from the x-ray, but the pain still occurs after encountering cold and cold. How to prevent and treat “old injury” pain Now that we have found the cause of the pain, how can we prevent or treat the pain that recurs after a bone injury? Recurring pain after bone injury can be prevented and treated, and early prevention and treatment can be more effective with half the effort. According to the theory of Chinese medicine, “if the limb is damaged outside, the qi and blood are injured inside, the camp and the guard are not consistent, and the internal organs are not in harmony”. Therefore, in the process of fracture healing, the simultaneous application of Chinese herbal medicine to regulate qi and blood and eliminate stagnation can promote fracture healing on the one hand, and reduce or even eliminate the possible recurrence of pain after fracture recovery on the other. Most people have the impression that after a fracture, all you need to do is to put a cast or surgery, put in a plate and screw, and then let the broken bone grow back on its own, and you don’t need to take medicine, just take calcium supplements. In fact, many patients often have the following two misconceptions about calcium supplementation: first, a lot of calcium after a fracture; second, more bone broth can supplement calcium. The fracture end will release a large amount of free calcium ions within two weeks after the fracture, plus the limb must be fixed after the fracture, increasing the chance of disuse decalcification, at this time, the calcium ion content in the blood will rise, if a large amount of calcium supplementation, the calcium content in the blood will exceed the body’s needs, but increase the burden of excretion of the kidneys. The healing of fracture mainly depends on the role of periosteum and bone marrow, and bone marrow can only function better under the condition of increased collagen. If a large amount of calcium is consumed within a short period of time after a fracture, it will increase the inorganic component of the bone causing an imbalance in the ratio of organic to inorganic matter, which will in turn affect the healing of the fracture. Therefore, it is best not to take any additional calcium supplements within two weeks of the fracture, but to add some vitamin D3 in moderation to help the absorption of calcium. In addition, an appropriate increase in protein to provide a comprehensive and balanced diet will help the healing of the fracture. Wait until two weeks after the fracture, then take appropriate calcium supplements. Bone broth contains mostly insoluble calcium salts, which are poorly absorbed by the body, and more fat, which will make people fat if they eat more. Therefore, calcium supplementation should choose milk, soy products, sesame paste, dark green vegetables small fish and shrimp and other foods that are rich in calcium and easily absorbed. Compared to calcium supplementation, the use of traditional Chinese medicine, under the guidance of traditional Chinese medicine, can not only regulate the local damage, but also balance the body’s qi, blood, yin and yang by regulating the patient’s physical condition, thus promoting the healing of fractures and reducing complications and “after-effects”. “. In addition, after recovering from a fracture, patients should also pay attention to proper protection of the injured area and carry out reasonable functional exercises to avoid cold that may lead to poor qi and blood flow.
