Vertigo

I have had intermittent bouts of vertigo for years, that last for different periods of time. I have never been given the dx of meniere's disease. I usually take antivert, which doesn't help much. I have been having daily spells lately, which make me nauseated. They are worse with movement. The last time my md said I had an inner ear infection, although I had no symptoms of that, ie, pain, fever, etc.

I read recently that this disease can be more frequent in persons who have auto immune diseases. I also have been diagnosed with sarcoidosis, which originally affected my lungs. Is there any validation of this, and does this affect the treatment/prognosis
