The Dizzyclear questionnaire has been developed by the author after examining and treating over 1200 patients successfully. It contains 20 questions with “yes and no” answers. After filling in the questionnaire on-line you will get an instant answer whether you are likely suffering from Benign paroxysmal positional vertigo (BPPV). It will also suggest whether you will benefit from home exercises using the Dizzyclear pillow.
