After a fracture occurs in the body, the healing of the broken end of the bone requires the consumption of more calcium than usual, and if there is not enough supplementation, low calcium can occur. When calcium ions drop, muscle tension increases, and thus cramps can occur. When cramps occur, it is important to take calcium supplements and eat more calcium-rich foods, such as ribs, eggs, shrimp, milk, and soy products. People with fractures should also drink more bone broth and chicken soup, preferably with less salt and water, and pay attention to supplementing vitamin C. Vitamin C can be supplemented mainly by consuming tomatoes. When sleeping at night, pay attention to elevating the affected limb to facilitate the blood circulation of the affected limb, thus reducing the occurrence of leg cramps.
