The American Hearing Research Foundation has some great info on their web site about post traumatic vertigo. I hadn't heard about that before and I learned a lot by reading that article, written by Timothy C. Hain, MD.
Here's an excerpt:
What is Post-Traumatic Vertigo?
Head injuries are sustained by 5% of the population annually. Post-traumatic vertigo refers to dizziness that follows a neck or head injury. While injuries to other parts of the body might, in theory, be associated with dizziness, in practice this is almost never the case. Because of the high incidence of litigation associated with post-traumatic vertigo, most clinicians are extremely cautious in making this diagnosis.
