First, your doctor will have you briskly lie on your back with your head turned to the symptomatic side at a 45 degree angle. This picture illustrates a treatment of the right side. Your head will be kept in this position for 30 to 60 seconds, based on the duration of the vertigo as measured by observation of your eye movements (for nystagmus). You will probably be dizzy for the first 10 seconds.
