Vertigo

• Vertigo is simply a feeling or sensation of dizziness. Vertigo is associated with a number of illnesses and conditions, but the general cause of vertigo is found in the human ear and in the vestibular nervous system. Anything which affects the structure of the inner ear, the vestibular nerve, the cerebellum or the brain stem has the potential to cause a person to experience vertigo. However, there have been cases of vertigo where the cause is unknown, as neither of these areas of the body were affected, but the dizziness still occurred.
  
  

Medications and Chemicals

• Vertigo is often caused as a side effect of certain chemical imbalances or medications that people may take. Certain pain relievers (such as aspirin), anti-convulsant drugs, antidepressants (amoxapine) and even prescription cold medication drugs may cause vertigo as a side effect when they're taken as medicine. In addition, certain chemicals like lead, mercury and tin can cause ototoxicity, which is an ear infection. This can result in damage to the acoustic nerve in the ear that will cause vertigo in the person suffering from this damage.
  
  

Medical Conditions

• Any number of medical conditions or injuries may cause vertigo as a side effect. A large number of chemical poisonings, especially bromide, lead, phosphine and gasoline poisoning have vertigo listed as a side effect. Vertigo may also be caused by seizures (partial or complete), whiplash injuries, basilar migraines and a slew of other conditions. Anything that can affect the makeup of the inner ear, or can adversely affect the vestibular nervous system, has a chance of causing a person to feel vertigo.
