Muscle spasm is a term that is commonly used to describe involuntary muscle contraction. As we all know the muscles contract and relax during bodily movement. In a muscle spasm, the affected group of muscles contracts abnormally and does not relax back to its original shape. Doing any strenuous physical activity for prolonged periods of time depletes the energy sources of muscles. Excessive use or overstretching of muscles and muscle injury are some of the most common causes that lead to uncontrolled contraction of muscles. As a result, the energy deprived muscles contract forcefully, leading to muscle spasms. Dehydration, spinal injury and medical problems like fibromyalgia can also trigger muscle spasms.
