In medicine a spasm is a sudden, involuntary contraction of a muscle, a group of muscles, or a hollow organ, or a similarly sudden contraction of an orifice. It most commonly refers to a muscle cramp which is often accompanied by a sudden burst of pain, but is usually harmless and ceases after a few minutes. There is a variety of other causes of involuntary muscle contractions, which may be more serious, depending on the cause. The word "spasm" may also refer to a temporary burst of energy, activity, emotion, stress, or anxiety unrelated to, or as a consequence of, involuntary muscle activity.
