Muscle twitches, also called fasciculations, usually only affect a single muscle. They're characterized by tiny contractions inside the muscle, caused by a nerve impulse. Muscle spasms, also called muscle cramps, affect multiple muscle tissues and are brought on by a chemical imbalance in the body.isorders of the nervous system can also cause muscles to twitch. These include nerve damage, fibromyalgia, muscular dystrophy and Lou Gehrig's disease. Along with muscle twitching, weakness in the muscles accompanies these disorders.
There are many possible causes of leg twitching. They may caused by simple fatigue of the muscle, stress, anxiety and even caffeine. Prolonged twitching may be caused by more serious medical conditions such as injury, nervous system disorders, certain medications, or excesses of heavy toxins.eg Twitching is often diagnosed as Restless Leg syndrome (RLS). Uncomfortable sensations in the legs, especially during rest cause the patient to voluntarily move their legs to remove the sensations. Involuntary movements of the legs during rest may be a sign of Periodic Limb Movement Disorder (PLMD).
