What is Muscle Twitching?
Muscle twitches are small involuntary movements involving small areas of muscle or muscle fibers. These twitches often go unnoticed, and when you do feel them, they tend to feel worse and more noticeable than they actually are. Twitches, also known as fasciculations, can occur in the arms, feet, fingers, hands, head, legs, stomach, and other parts of the body. Twitches can also occur in the eye muscles. Muscle twitches are usually harmless and are more of an irritation than a cause for concern. In most cases they disappear shortly after they appear or when the underlying cause is seen too. In some rare cases, however, muscle twitching can be a sign of a neurological disorder.
