I have vertigo too, its commanly associated with MS but there are many many other causes. I have Lupus brain lesions which the doctors attribute to my memory loss, speech and cognative issues, tremor and vertigo. Their is a medication for the vertigo i can't remember the name but i declined to take it because the side effects seemed worse than the vertigo alone. Have you ever had a brain MRI?
