What happens inside the body when you get a crick in your neck or when you pull a muscle? What exactly is a knot, e.g., you have a knot in your shoulder?

There are two basic causes of cramping. One is inadequate oxygenation of muscle, and the other is lack of water or salt. Cramps from poor oxygenation can be improved by rapid deep breathing, as well as stretching the muscle. Cramps from lack of salt and water can be treated by stretching the muscle, and of course drinking water and increasing salt intake. Pounding on the muscle can increase soreness. http://en.wikipedia.org/wiki/Cramp Jun 23 06, 7:56 PM
