General Discussion

Neuromyotonia is a rare neuromuscular disorder characterized by abnormal nerve impulses from the peripheral nerves. These impulses cause continuous muscle fiber activity that may continue, even during sleep. The disorder, which has both inherited and acquired forms, is characterized by muscular stiffness and cramping, particularly in the limbs. Continuous fine vibrating muscle movements (myokymia) can be seen. Muscle weakness may also be present. Muscle relaxation may be difficult especially after physical activity involving the particular muscle(s).
