What causes muscle spasms?
Muscle spasms and cramps occur when a muscle contracts involuntarily and painfully. There are a number of causes of muscle spasms, ranging from nutritional deficiency to serious nervous system conditions. The process of moving a muscle is actually quite complex, although you may not be aware of it. It involves sending a signal from the brain through the nervous system to the muscle in question. An ornate series of chemical reactions and communications will ultimately result in a contraction of the muscle, causing it to move. Millions of involuntary muscle movements keep your blood circulating and your lungs moving, even as you sleep. If this process is disrupted, the result can be a muscle spasm. On the brain’s end of the deal, muscle spasms can be caused by neurological disorders or conditions such as strokes. Damage to the nervous system may also cause muscle spasms; many toxins, for example, attack the nervous system. Metabolic disorders can also be responsible for muscle spasms, by
