I am a 56 year old female. I have been nauseated for over two weeks, can hardly pick up my head to do anything. when I stand the room spins, I have fallen once and I am very unsteady. I am a migraine sufferer, I take 150 mg Topamax and lisin/hctz 20-25mg for high blood pressure. I notice that I have occasional jaw pain and have been treated for vertigo in the past two years. but this does not feel like vertigo, nausea is very dominant. What are your thoughts? Thank you
