Fasciculation

The sudden, short, involuntary muscle fiber contractions are known as fasciculation or muscle twitching. Most minor muscle twitching is of less concern. However, it can occur in healthy people due to less severe causes like increased caffeine intake, stress, inadequate sleep, physical activity, nutritional deficiency, local irritation (eye twitching), nicotine, certain drugs, dehydration, etc. After that, they resolve on their own. More severe causes include Lou Gehrig's disease, muscular dystrophy, etc. Treatment to ease the symptoms includes corticosteroids, muscle relaxants, and neuromuscular blockers.
