They are not injured, they are not sick, they eat, play and study as usual, and they do well in sports, but they often complain of leg pain. After a night’s rest, they went to school the next day as usual. In the past, they did not feel any discomfort in their legs, and there was no redness, swelling, heat or pain in any part of their legs, including the knee joint, thighs and calves. The actual meaning is that it is not a disease, but a common temporary phenomenon in the process of growth. Of course, it does not require treatment and will heal naturally in time. We can summarize the characteristics of growing pains as follows: 1. Normal general health and normal physical activity. The pain is mostly late afternoon to night, with no symptoms the next morning. May have prolonged episodes, but does not affect growth and development. Good motor ability. 2. There is no local redness, swelling, heat or pain in the painful area, and no pressure pain. There are no fixed pain points at all, that is, the child can not say which part of the pain. x-ray or other examinations without lesions. 3. Fat children, active children, fast growing children and those with heavy calf bending are more likely to have growing pains. Since growing pains are not a disease, it is not possible to talk about treatment. But what can parents do for their children when they are in pain? Should they limit the amount of exercise? First of all, parents should make sure that the child rests, and they can help the child to do leg massage. The specific practice is: massage from the foot up to the knee, massage the calf stomach, and insist on doing it for ten minutes every night, and do it anytime when it hurts, which can accelerate blood circulation in the legs and reduce leg pain. As for the arrangement of exercise for children, our principle is: encourage exercise and avoid overwork. The purpose of encouraging exercise is to strengthen the leg muscles in order to gradually achieve the ability to keep the knee joint stable and balanced, so that the leg pain disappears. However, if the activity is too much and overworked, it is no longer able to support, but will aggravate the instability and produce pain. It even makes the joint and ligaments injured and becomes chronic strain. The consequences are quite serious and go far beyond growing pains. Even so, parents should not be overly distressed and pampered by their child and not allow him to exercise at all. The child’s sense of self-protection is reliable. In short, it is to help remove the objective factors that predispose to growing pains. As the muscles strengthen and stabilize the knee joint with age, the leg pain can gradually heal itself.
