What is the reason for the midnight calf cramps?

Sudden muscle spasms at night may be caused by vitamin D deficiency rickets, which is specifically caused by anorexia, partial eclipse, lack of light, and insufficient vitamin D and calcium content caused by outdoor exercise. In addition, if the child develops rapidly, it may also occur due to excessive consumption of these nutrients, and the child's knee joints and front legs may frequently experience pain. In addition, if the child has had strenuous exercise before going to bed or caught cold at night, it may cause rapid muscle contraction and pain in the static state, but proper massage can alleviate it.
