Hi, @shuvhfa1 - welcome to Mayo Clinic Connect. Since you were talking in your post about internal shaking, I moved your post here to this discussion on internal vibrations so you could talk with others who have had similar experiences. Please meet @hopeful33250 @jager5210 @asquires @redladyjoni @2016dodge, who may recognize the vibrations you are talking about as well as the "tremor attack."

Are you differentiating the internal shaking and a tremor as shaking not outwardly visible and shaking that is outwardly visible?
