Finally! Someone else like me on here! Yes, I’m 55 and have the same. The myoclonus finally went away after my two initial clinical exams which were normal. EMG on the 29th. My symptoms started after an extremely stressful summer: My soul dog passed away, one son broke his leg and the other left and returned from college. Twitches mostly in calves. In my opinion, I think many people of all ages develop this as an anxiety/trauma response. I also think it’s under diagnosed or under reported overall. Did your husband have an injury or period of stress this year?
