Myoclonus (body jerks, twitches, spasms)

I've been having myoclonus for over a year now. Body jerks, arms legs, torso & internally as well feels like a sudden cramp/spasms of your insides or a fluttering. I am taking Clonazepam very low dose at the moment. And also in Peri-menopause. Has anyone had any success using HRT to reduce their myoclonus? Could it be hormone related? Or any other advice. No specialists are interested in helping me as my MRIs are clear.
