Benign fasciculation syndrome (BFS) is the generalized term to describe muscle twitching when it does not stem from a nervous system disorder, such as Lou Gherig's disease. Benign fasciculation can often cause high anxiety, because the cause of the twitching is unknown. However, benign fasciculation is not accompanied by muscle weakness or loss of feeling, which can be signs of something more serious. Usually, a doctor rules out the possibility of nerve damage with an electromyogram (EMG) scan of the body to make sure the muscle twitching is benign.
