Vertigo is a symptom in which a person feels that either he or his surrounding is continuously moving or spinning. One may also experience nausea, vomiting, sweating or abnormal movements of the eye.

The leading cause is the loss of balance in the inner ear. Some problems of the brain may also cause it. Causes of vertigo are infection of the inner ear, migraine, inflammation of the vestibular nerve sending signals from the inner ear to the brain to maintain balance, hole in the inner ear, tumours, head injury and certain head movements.

Motion sickness is the uneasiness and feeling of nausea and vomiting while travelling, whereas vertigo gives the same symptoms even when you are still. While the lack of agreement between the sense organs like eyes and ears cause motion sickness, vertigo occurs due to the lack of balance in the inner ear.

Certain head movements, change in the position and instability are the common triggers of vertigo. However, the triggering factors may be different in different people. The following are some movements that may trigger vertigo: bending down, getting up from a lying down position and looking upwards.
