A spasm is a sudden muscle involuntary contraction, a group of muscles, or hollow organs like the heart.
Spasmodic muscle contractions can be caused by many medical conditions, including dystonia. Most often, it is muscle cramps accompanied by sudden bursts of pain. Muscle cramps are usually harmless and stop after a few minutes. Usually caused by imbalance of ions or excess muscle.
There are other causes of unconscious muscle contractions, and some of them can cause health problems.

Description and causes
Various kinds of unconscious muscle activity can be referred to as "spasm".
Spasm may be muscle contraction caused by abnormal nerve stimulation or by abnormal activity of the muscle itself.
A series of seizures, or permanent seizures, is called "spasm".
Spasms can cause muscle strains or tears in the tendons and ligaments if the power of spasm exceeds the tensile strength of the underlying connective tissue. This can occur with very strong seizures or with weakened connective tissue.
Hypertonic muscle spasms are a condition of chronic and excessive muscle tone (ie, resting muscle tension). This is the amount of contraction left when the muscle does not work. The actual hypertonic spasm is caused by a non-functioning feedback nerve. This is much more serious and permanent unless treated. In this case, hypertonic muscle tone is excessive, and the muscles can not relax.
The seizure subtype is colic. This is an episodic pain caused by spasms of smooth muscle in certain organs (eg, bile ducts). The characteristic of colic is the sensation of having to move, and pain can cause nausea or vomiting.
