I just recently had a episode of nausea, and vertigo, it was the most scariest thing I ever had. I have had already been to the ER, and they even took a MRI and could not find anything and also have seen my Dr. and he said that it could be the inner ear, since then I have had 3 more episode, one that lasted for 3 hours, and Friday I will be going to a specialty, but, in the meantime I want to know more.... please help, I m very scared since May 11th I have been fine. Thank you
