Welcome Avash, 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 @jager5210 @asquires @redladyjoni @2016dodge and others, who may recognize the vibrations you are talking about as well as the "electrical current flowing feeling.

I'm not sure if you know the underlying cause yet. You may be interested in these related discussions:

Have you been to see a neurologist about this issue? What do the suspect to be the cause?
