Muscles are made up of elastic fibers that not only give general shape to the body, but also contract to move its various parts. The body gets its frame and shape from the skeleton muscles. These are voluntary muscles. The contraction of these muscles is consciously determined by the living being. In other words, living beings have total control over their body.

But sometimes, these voluntary muscles contract involuntarily. In the process, they tighten the muscles and generate pain, making it hard to move that part of the body. This kind of untimely involuntary, violent contraction or knot in the muscles is called a Muscle Spasm.

In short, muscles flex and extend in the affected part of the body at the same time. This generally results when the muscle is under 'pressure' or is overused. A Muscle Spasm attacks a whole joint, leaving that part of the voluntary muscle in a state of 'shock' for some time. It may begin as an awkward sensation that soon spreads in the affected area. The muscles in that whole area then become so tight and stiff that they hurt severely. The most recommended instant aid is to put ice on the affected area, and stretch it. Muscle Spasms mainly affect arm, neck, leg and other such joints that are flexible to reflexes and movements.

Muscle Spasms mostly occur due to excessive use of the muscles. This may be strenuous exercise, stress, muscle fatigue caused by unused muscles for sometime, and dehydration resulting from loss of body fluid. Muscle Spasm may occur from an injury, accident or even muscle diseases. It may also occur if one does not make use of the body muscles and joints regularly, affecting its function. For instance, many older people restrict the movement of their body. This makes the usually flexible, voluntary muscles and joints become rigid. As a result, any minor stimulation makes them susceptible to spasms. Hence, in order to reduce the chances of Muscle Spasms or cure an attacked body part, one needs to follow a range of stretch exercises. There is supportive medication for Muscle Spasms. But the best method is to take a balanced diet, follow an exercise regime, and check on stress and strain. There should also be the required amount of calcium, phosphate, sodium, magnesium and other essential vitamins and minerals in the diet. Even though Muscle Spasms are known to cause tight knots in the muscles, reducing flexibility to control movements voluntarily, it is found to retain the muscle strength intact.
