Fasciculation and cramps can be seen both in healthy individuals and in those with fatal diseases, such as Amyotrophic Lateral Sclerosis. We present a 27-year-old male patient, professional soccer player with fasciculations and cramps in bilateral gastrocnemius-soleus complex. The patient complained about having to stop playing soccer because of muscle cramps and twitches in both calves, which had started 3 years earlier. After completing all laboratory and electrophysiological examinations, the patient was diagnosed as cramp-fasciculation syndrome. The aim of this paper was to present a rare case of cramp-fasiculation syndrome and discuss if the syndrome is benign or pioneer of a severe pathological process.Cramp Fasciculation SyndromePeripheral Nerve HyperexcitabilityFasciculationCrampIsaac's SyndromeArticleWOS:000376566800029
