Post COVID: Anyone experiencing internal vibrations?

I have had long covid for over two years and a symptom began sporadically during the initial seven weeks that has worsened since a second covid experience. It began as a “flutter” in my chest upon waking, lasting 5 seconds or so. It is not painful just a new sensation I have never experienced. After getting covid again in February 2022, the internal vibrations have become full body and go on for forty seconds. It is always upon waking or falling asleep temporarily during meditation and waking again. Long Covid retired me from my profession and I am not under any stress. I had a recent cardiac incident (also due to long Covid) and wore a Holter monitor. I triggered it whilst having an IV incident: definitely not cardiac induced. Has anyone else experienced IV like this?
