Over the past couple months I have had dizzy spells. They are often brief. Only for a minute or so. i have to immediately sit. I haven't had to throw up and didn't necessarily feel nauseous. but during these spells i would start to hear a kind of white noise in my ears and head. It only lasted for as long as the dizzy spell. I don't have any inner ear issues or balance issues or menieres disease or tinnutis. I don't take any meds and sometimes i take an over the counter sleep aid at night to sleep. And i have a normal diet. Its not anxiety.
