I have had vibration in my body for I believe about 18 months now. While I can't speak to anyone else's experience for me it is NOT muscle twitching or over activity etc. that would be in line with myoclonus. It only happens when I lay down to go to sleep and when I wake in the morning for the first few minutes (that I'm aware of). Mostly in my extremities. I liken the feeling more to the vibration you would feel if you put your hand on a refrigerator when it is running... a humming. More intense some times, less so others.

I haven't been to a specialist as of yet. In the beginning it was upsetting but now is the new normal. Most Doctors I have spoken to have just said they've never heard of that. I've requested and have been referred for a sleep study as a starting point.

That timeline does coincide with when I began began receiving the Covid 19 vaccine and I would agree that since that time I have had the issue with vibration and inflammation and joint pain, but correlation doesn't always mean causation. However I never had either of these issues previously. I have been put on a couple doses of steroids for the pain during that time.

Wish everyone the best in their healing.
