Is it vertigo?: There are many causes of this and there is no substitute for a physical exam and interview by a thorough doctor to help figure this out. When that is not available, you have to consider whether moving your head makes this feeling worse. A common cause of these symptoms is peripheral vertigo. This causes short episodes of symptoms like yours and it often feels worse with certain head movements.
