I feel off balanced out of the blue and dizzy too
If you are dizzy and off balance there IS a chance you may fall down the stairs.

It could be caused by any number of things and you should see someone about it.
Let us know how you make out.
sorry had to clear this up... i am bothered by it very much and very scared
