I have a spouse that is having vertigo. She is experiencing the room spinning mostly at night and some in the day. Smells bother her at times and she gets dizzy as well when not spinning. Today is the 5th day of this and she is unsure of what is going on. She has been stressed lately, and a bit dehydrated as well. But, nothing out of the ordinary. This came on suddenly. She experience something like this a year ago when a bit dehydrated as well, but that went away within 2 days. The same feeling of spinning in the night and dry mouth, but no specific stress issues at the time. Do you have any advice for this situation? Thanks.
