I know there are crystals in ear canal that get out of place that can cause balance issues. It sounds like your wife's issue is too bad for this to be it.
my wife has had the crystals in her ear out of place ..she can only lay on her left side ...gets dizzy in different ways ..they didn't see this right away because they usually get dislodged when you have some kind of head injury ...she didn't ...she had to go to physical therapy where they got the crystals back where they belong ..she was good for almost a year and has had to go back ..she is well now but who knows about the future ..God bless
