What causes growing pains has also been the subject of many different opinions over the years. It is generally believed that growing pains occur because the growth rate of long bones is faster while the growth rate of muscles and ligaments is slower, that is, the growth rate of long bones is not synchronized with the growth rate of ligaments and muscles. During this growth process, the muscles and ligaments are stretched and cause pain, so it is clinically manifested as growing pains. Other scholars believe that growing pains are related to bone metabolism and bone density level. Some parents also make their own decisions and buy some antipyretic and analgesic drugs for their children at pharmacies. In fact antipyretic and analgesic drugs have a lot of side effects besides pain relief, especially for young children, which can cause great damage to liver and kidney. Therefore, we remind you that if your child has pain in the lower limbs, you must take your child to a regular hospital for examination to exclude other diseases. For children with growing pains, parents can give their children appropriate calcium supplements, which can inhibit muscle pain and spasms caused by overexcited nerves and achieve relief. In addition, parents can give their children hot compresses, massage and other treatments. If the pain is very severe, the child can be allowed to reduce the activity and let the muscles fully relax and rest. Or tell the child more stories, play games or toys before going to bed at night to distract the child’s attention, which can reduce the degree of pain.
