When I hit the reply button it just refreshes the page. Oh well. I HAVE myoclonus (several different kinds methinks) and some other movement problems (tremors, ect). I don't know alot about movement disorders and I was hoping you could educate me a little. What's the difference (if any) between myoclonus and fasciculation. I have entire groups of muscles (like my bicep) suddenly jumping and I have no clue how to classify that. Also, do you happen to know what a myoclonic tremor is?
