I also feel the vibrations at night, but just in my legs like restless leg I’m guessing. I need to keep moving to a different position. It has just started and it’s not every night thank god. There are days my legs feel very heavy too. I haven’t had any falls as of yet. I’ve had the full body tremors if I’m standing to long and can’t sit or lean on something. This disease really sucks the life out of me. I wish some doctors would work with us more and figure out what is causing it.
