The sensation of spinning or revolving while the body is stationary with respect to the earth or surroundings. Medical conditions affecting the inner ear, which is responsible for our sense of balance, can cause vertigo.
The sensation of vertigo can evoke feelings of anxiety. While anxiety itself does not produce vertigo, vertigo from another cause can be made much worse by anxiety. People with certain anxiety disorders, such as panic attacks, can sometimes also experience vertigo.
