The symptoms of vertigo include a sense of spinning or moving. These symptoms can be present even when someone is perfectly still. Movement of the head or body, like rolling over in bed, can escalate or worsen the symptoms.
The symptoms of vertigo are different from lightheadedness or a sense of fainting. Many people experience associated nausea or vomiting.
Physical examination often shows signs of abnormal eye movements, called nystagmus. Some patients experience imbalance in association with the vertigo. If imbalance lasts for more than a few days, or if the vertigo is accompanied by weakness or incoordination of one side of the body, the suspicion of stroke or other problem of the brain is much higher.
