Hi everyone. I also am experiencing what I associate as internal tremors (vibrations) for over a year now. For most of the year, I have thought it to be from an external source. but after experimenting I can conclude that it is an not caused by an outside condition. Here is how I describe my symptoms:

- a buzzing or vibrating sensation similar to a haptic feedback from games and phone on vibrate mode. It felt like my bed and the walls were also vibrating (based on touch)
- the sensations occur in the head, inner-ear (tinnitus got a lot worse), face, shoulder, arms, legs (quad area), back
- sometimes it can be pulsing or sometimes it goes in waves
- i can sense the vibrations in the back of my head (skull)
- spasms in the abdomen area (gut)
- it caused me tremendous anxiety and stress not knowing exactly what's happening. I thought it was from electromagnetic waves or even sound waves.
- it's the worst at night and I wake up unable to sleep. Sometimes I can't sleep at all and I have bouts of insomnia for almost two weeks until I couldn't take it anymore and left my home
- moved away and for some reason it disappeared. Thinking that it was gone I decided to go back home. The anxiety came back not knowing if it was going to happen again (it did).
- I moved to another house because I couldn't deal with my own place
- The last 3 months has brought me clarity. The tremors and vibrations in the new environment didn't go away this time but I was able to ignore it most of the time and was able to sleep.
- This is when I started looking into possible neurological causes or disorders. This is how I assumed that it's stress induced "internal tremor".
- I slowly started easing myself into what I thought was a hostile environment (my home). I can now sleep in my own bed again.
- I have yet to see my doctor but I do plan on getting some tests for PD or MS for even more clarity on my situation. I'm also considering tests for detecting hormone imbalances, systemic inflamation and heavy metals.
- The worst thing about this has been the anxiety and stress that it generated due to it being invisible. That prevented me from being able to sleep. It's the lack of sleep that has caused me to breakdown.

Feel free to ask me any questions. I hope everyone here stays strong and you are not alone.
