Vertigo is not, actually, fear of heights. It's a type of dizziness, a feeling of motion when one is stationary.[The symptoms are due to a dysfunction of the vestibular system in the inner ear. It is often associated with nausea and vomiting as well as difficulties standing or walking. The most common causes are benign paroxysmal positional vertigo and vestibular migraine while less common causes include Ménière's disease and vestibular neuritis. Excessive consumption of ethanol (alcoholic beverages) can also cause notorious symptoms of vertigo. You can manifest it through thoughts, but it really any cause of inflammation such as common cold, influenza, and bacterial infections can cause transient vertigo if they involve the inner ear, as may chemical insults (e.g., aminoglycosides) or physical trauma (e.g., skull fractures). Motion sickness is sometimes classified as a cause of peripheral vertigo. Motion sickness is one of the biggest symptoms of vertigo and it develops most often in persons with inner ear problems. The feeling of dizziness and lightheadedness is often accompanied by nystagmus. This is when the eyes rapidly jerk to one side and then slowly find their way back to the original position. During a single episode of vertigo, this action will occur repeatedly. Symptoms can fade while sitting still with the eyes closed.
