Leg pain may be due to growing pains caused by growing taller, or it may be due to calcium deficiency or epiphyseal inflammation. 1. Growing pains: people may have growing pains while growing taller, which is related to the fast growth of long bones and high activity, resulting in leg pain. 2. Calcium deficiency: people may experience abnormal nerve excitability after calcium deficiency, leading to leg muscle spasms, thus causing leg pain, which is not related to growing taller. It mostly occurs in children, adolescents or the elderly during the growth and development period. 3. Epiphyseal inflammation: If people run and jump a lot or catch a cold during the growth and development period, epiphyseal inflammation may occur. The inflammatory reaction caused will lead to leg pain rather than a precursor to growing taller. When people have leg pain is not necessarily grow taller, it may also be caused by other diseases, people should go to the hospital in time to check, clear the cause, if it is a disease need to be treated in time.
