Vertigo should not be confused with symptoms of lightheadedness or fainting. To determine if true vertigo exists, you must describe a sensation of disorientation or motion. In addition, you may also have any or all of these symptoms: Nausea or vomiting, sweating and abnormal eye movements. The duration can be from minutes to hours and can be constant or episodic. The onset may be due to movement or change in position. It is important to tell your doctor about any recent head trauma as well as any new medications you may be taking. You may have hearing loss and a ringing sensation in your ears. You might have visual disturbances, weakness, difficulty speaking, decreased level of consciousness, and difficulty in walking.
