I have not been dxd, but have been experiencing ms symptoms and am awaiting Neurologist appt. I can definitely relate to the vibrating sensation, which I have felt in feet, legs, arms, hands, shoulders, head and face, and even, on one occasion, in my teeth! This was the most disturbing, and it seemed that when I spoke, the vibrations resonated in my head - very wierd! Sometimes the vibrations are brief, like someone pressing a buzzer; other times they are constant. If I had to describe them to anyone else, I'd be afraid they would think I was crazy. It helps me to know tht others are experiencing the same, and that I'm not losing my mind!
Good luck with everything.
