Classically, generalized true fasciculations could be due to motor neuron diseases, benign fasciculations, and hyperthyroidism. If not yet done, get thyroid studies completed. If you possess a lack of confidence in currently involved physicians, get a second opinion from a neuromuscular specialist.
