Illygnophobia

Illyngophobia is the fear of vertigo (or dizziness).

Those with illyngophobia avoid activities that induce dizziness, such as riding certain amusement park rides, and suffer from the symptoms of a panic attack when they do feel dizzy. This phobia is similar to acrophobia in the sense that illyngophobic people are afraid of high places. The main difference between the phobias is that illyngophobes are afraid not of the heights themselves, but of developing vertigo when looking down.
