Hi there, i have just joined this group because i would like to know more about Myoclonus, i have severe tremors in my lower back, but only at night, this can happen between 1 and 6 times a night and last from 10 seconds to 2minutes, it never happens during the day (which is good) I have been to the Doctors and have been sent for Physiotherapy and now a course of Acupuncture, but have not been diagnosed with anything, can you help please.
