Have menieres and vertigo. Barometer pressure changing normally affects my balance & head pressure, sometimes migraines. Symptoms last 3 days am, hot flash, feel like passing out any minute and nauseated/some vomiting. Suggestions besides cold wash cloth back of neck/face? Sugar is fine, type 2. Not dehydrated, don't think anxiety attack either, and blood pressure has been fine. I don't have a pressure cuff to take it though.
