I am very sorry to hear about your symptoms. Dizziness can be a frustrating problem, and I am glad that you have been working with your doctor
to determine the cause. It is important to understand exactly what you mean by "dizziness," as there are several distinct classes of possible problems-- vertigo, presyncope, or nonspecific dizziness. Vertigo is commonly described as a spinning sensation, sometimes causing instability with walking, and is usually made worse with head movement. There are many causes of vertigo, but given your history of a sore throat
, your symptoms would most likely be caused by a post-viral infection of the inner ear. Unlike with a bacterial ear infection, the inner ear may look normal on examination. A post-viral ear infection (called vestibular neuritis or labyrinthitis) should resolve over the course of weeks, but there are several medications (such as meclizine) that can control the symptoms in the interim. If your dizziness is better described as lightheadedness or near fainting-- especially notable when standing-- you may have presyncope. This would most commonly be caused by dehydration (especially if you were drinking less with your sore throat), but if you have a history of heart disease further evaluation would be warranted. Finally, nonspecific dizziness is notoriously hard to describe, but is generally thought to be related to anxiety
, depression, or other psychiatric disorders. I would recommend discussing some of the above possibilities with your physician, and sincerely hope that you recover soon!
