Dear Yahia: Vertigo may be caused due to a lot of conditions. Benign paroxysmal position vertigo, vestibular neuritis, meniere's disease, migraine, acoustic neuroma and certain medication all cause vertigo. You may need to consult your doctor for examination and tests to determine the cause of the vertigo.
