In the clinic, we often encounter children who have entered puberty or children treated with growth hormone who have rapid growth and have painful swelling up and down their knees or calves, and even children who are in so much pain that they can’t sleep, and parents can only help rub them to make them sleep. What is growing pains? How to deal with it? The child was 9 years old and recently said he had pain in his knee or lower leg before going to sleep, but the temperature was not found to be elevated, so the parents worried that there was a problem and took the child to our orthopedic department the next day to have a checkup. x-rays were taken and no problems were found, especially to reassure Wang that no tumor or anything was found, so what was the problem? In fact, this is a very common problem among school-age children – growing pains, which about 10-20% of school-age children can experience. They often have discomfort at dusk, which can be severe enough to interfere with the child’s sleep. Children often describe it as muscle pain or indescribable swelling or cramping pain. Some patients even describe sensations such as gastrocnemius, tibial or femoral nerve spasms, while various blood muscle enzyme profiles or x-ray findings are completely normal, and physical examination does not reveal any abnormalities, especially importantly, no joint compression or joint hypermobility. Generally, children can tolerate it, and the symptoms will be reduced or disappear after a little massage. So what exactly causes this is not very clear. According to our analysis of dozens of cases of growing pains that occurred during the growth hormone treatment period, we found that a significant number of children (more than 90%) had growth pains when their growth rate reached more than 1 cm per month, which indicates that the rapid growth of bones is pulling on the muscles. Some experts believe that the pain may be caused by the pulling effect on the periosteum. However, it has also been reported that these children often have a family history and are somewhat hereditary, which could explain the fact that only some children are prone to growing pains, and when asked carefully their parents may also have growing pains. What is the best way to manage growing pains? Generally, parents do not need to use special measures for growing pains, and conservative treatment is the mainstay. If it is really necessary, one NASIDS painkiller every night will usually be effective. However, it also indicates the arrival of rapid bone growth period, which is good news. At this time, parents need to pay attention to a balanced diet for their children, eat more nutritious foods, and take VitD and calcium supplements if necessary. It is necessary to let children get more sunlight and increase sports and exercise appropriately and scientifically to make the bones grow stronger and avoid osteoporosis.
