Hello, I know this is an old thread but I am hoping someone is still looking at it. Last May, after an upper respiratory illness, I started having what I thought were episodes of motion sickness. 8 months and $25,000 in med charges later, I am still not well and don't have a diagnosis. My "episodes" are now waves of pressure rising and lowering in my head almost constantly and sometimes for an added bonus I walk with a drunk stagger, and since everything else has been ruled out (MRI normal, CT normal, ears normal, ENG normal, not vertigo, not meniers, not aied, etc. ) they are guessing Vestibular Migraines. They started me on Topamax 2 weeks ago and no improvement yet. Can someone please give me something to go on? Any advice is appreciated. Thank you.
