If a spasm is forcefully sustained and doesnât relax, then it ripens into a cramp. A charlie (charley) horse is a common term many use to indicate they either have a muscle spasm or cramp, typically in a thigh or leg muscle. This charlie of a horse is very often caused by dehydration and/or lack of potassium. A muscle spasm can occur in any muscle and you may be able to see or feel the hardened muscle, like a knot. Sometimes, muscle spasms will occur with such force that theyâll leave a bruise behind.
Skeletal muscles that cramp the most often are the calves, thighs, and arches of the foot, and are sometimes called a  Charley horse  or a corkie. Such cramping is associated with strenuous physical activity and can be intensely painful; however, they can even occur while inactive/relaxed.keletal muscle cramps may be caused by any combination of muscle fatigue, a lack of electrolytes (e.g., low sodium, low potassium, or low magnesium) . Cramps of smooth muscle may be due to menstruation or gastroenteritis.
