Spasms in muscles is always an unpleasant phenomenon. Those who suffer from the lack of magnesium are more likely to have issues with muscles. They complain of the frequent cramps in these areas. If you find yourself suffering from spasms without doing too much sport or walking all day long, it might be the clue. The process of muscle calcification leads to the inability to do daily exercises and even bad sleep behavior. Because of the aging, additional calcium gathers in the muscles, which causes painful cramps.
