Vertigo is a symptom rather than a condition itself. It's the sensation that you, or the environment around you, is moving.
If you have vertigo, you may feel as if you're moving even when you're standing completely still.
Other symptoms of vertigo include:
- feeling sick
- difficulty standing
The symptoms of vertigo can be barely noticeable or so severe that the loss of balance prevents you from perfoming everyday tasks.
Depending on the cause, an episode of vertigo may last several seconds, minutes, hours or days.
Vertigo is not a fear of heights.
