I started feeling the same thing about four months ago and cannot figure out what it is. I've gone to a cardiologist and had several test done and they were all normal. I've gone to get checked for carpal tunnel syndrome and was negative. I am also very concerned and puzzled by this vibration. My general doctor seems to think it's all in my head. Have you found out anything yet?

Hi, Just to let you know that its not in your head, i have a similar eaxperience, & still looking for some answers myself

omg i have had this for two months and the docs tell me its in my head...its a horrid inner vibration at the base of my neck and upper back, sometimes i can see my stomach pulsating too.....extensive testing, all normal.......this is insane.......maybe a reaction to meds?
