what kind of tremors do you have? the thing that happens to me sometimes, not on a regular basis , is when i'm lying down, i feel like my legs are shaking but they are not moving at all, it feels like the bed is even shaking, but i'm lying still..strange..sometimes my whole body will get these internal vibration/tingling, it gets overwhelming, that can happen when ever it feels like it. i wish i lived closer to a place like mayo clinic (8hrs from me)...i'd try to get into one of the long covid things ..there is nothing here..so i just get through it...
