My friend is a scientist. She was hit by a truck three weeks ago and is lying down with headaches and vertigo.

She has observed that

1. Rotation is always in the same direction
It is the same direction whether eyes are open or closed.
2. Sometimes the rotation is 360deg
Sometimes only rotates 30deg
Sometimes rotation stops. room is fine.
3. She has one position in which she can rest with a little more comfort.

My friend would like to know if a Vertigo specialist could give her some information from these observations.

It seems to me that if the vertigo stops at times, the nerve cells cannot be damaged, and if rotation is always in the same direction, probably only one ear is affected.

Any suggestion as to how to find a specialist who knows about vertigo symptoms?
