http://adorablesoul.com - One of the most common types of cramps that are experienced is in the legs. These cramps are the result of the painful and spontaneous contraction of the muscles below the knee. Generally, these cramps occur in the calf or foot and most of the time they occur at night. Older people tend to suffer more from leg cramps but have also been observed in younger people. Although leg cramps, or also referred to in North America as Charlies Horse, are very common, the investigations that have been performed are not extensive enough to reach a conclusion about a specific cause. However, some other studies show that there are certain risk factors that can increase your chance of developing these cramps.
