Vertigo, Dizziness, and Dysequilibrium. These words mean different things to different people. However, if you are using these words in the medical sense of things, understanding the definition will help you communicate more precisely when talking with your doctor or physical therapist.
VERTIGO is a spinning sensation, either that you are still and the world is spinning, or that the world is still but you are spinning. If things aren’t spinning, then saying you have vertigo is not quite right.
DIZZINESS has to do with a funny feeling in the head, but nothing is spinning.
DYSEQUILIBRIUM has nothing to do with dizziness, or vertigo. People with dyequilibrium have no dizziness or vertigo, but they are unsteady walking.
Hopefully these definitions will help you in explaining your symptoms!
