My body suddenly jerk when I am doing anything and also have twitching all over my body please help.

Myoclonic twitches or jerks usually are caused by sudden muscle contractions, called positive myoclonus, or by muscle relaxation, called negative myoclonus. Myoclonic jerks may occur alone or in sequence, in a pattern or without pattern. They may occur infrequently or many times each minute. Let's have a detailed discussion for better advice and medication plan.
