I have been light headed for about 3 yes now.i had my 1st case of vertigo then. I also was having shortness of breath after going through a lot of series of events with different Dr they said I suffer from anxiety. Even though I might have sum stress I don't think I have it. I also was put on a cap machine arrive from all of the series of events. I stopped using this machine after about a year with out having any problems. But here's the problem for about 6 months I been light headed all the time about 75% of the day.i feel like crap.the best way to describe it is it feels like I have a hangover or like I have a virus without stomach pains.i feel nausea without the feeling of throwing up.now I'm having headaches. Which started about 2 months ago. About 3 months ago I had a c scan of my head but didn't find nothing. At that time I had a infection in my tooth but had I taken out.i thought it was my high blood pressure medicine I was taking divan and my Dr change it but still have the light headedness.i went a e.n.t. found nothing. About 7 years ago I had a fusion on my neck c5-6.this is the only Dr I haven't seen yet. I feel like shit all the time. Need help Dr have no idea
