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?

@avash Hello and welcome. Thank you for joining the conversation about internal vibrations, they are annoying, that's for sure. I hope you've taken time to review others accounts in this conversation, and gained insight. I have experienced vibrations due to Small Fiber Neuropathy. How long have you been experiencing internal vibrations? Where do you feel them? Have you been seen by a neurologist yet?

Yes and mine is caused by a rare neurological disorder called Hereditary Nerve Pressure Palsy, it also falls under Charcot-Marie Tooth (CMT). I get electrical flowing feelings every now and then mostly in the left side of my chest and near my groin on the right side. Once I thought is was my cell phone on silence, just vibration. It is a very weird sensation. Now I'm getting internal vibrations through my entire body. My body does not shake I just feel it inside. I hope this will help. I would definitely recommend seeing a Neurologist and suggest Genetic Testing. This is how my condition was found, otherwise I would still be going crazy looking for answers. Good Luck and I hope you find the answers.
