It's a type of vertigo, the full name is Benign Paroxysmal Positional Vertigo. Last Tuesday I was in Iceland, my flight was at 5 PM. I woke early and got up to go the bathroom. Everything started spinning and I just went to lay down again. Eventually I found that if I moved slowly I could get up. I figured I was hung over even though I wasn't feeling nauseous and my head felt fine. I got my stuff together by moving slowly and packed, had breakfast and decided to take a nap. I laid down and the spinning started again. I quickly changed which side I was lying on and that helped. I went to the ER and the doctor said I have BPPV and made me do these exercises ( not really an exercise ) called the Epley maneuver, that was rough because it would bring back the feeling. She said I could fly. I was fine on the plane but just freaked out by it all. On Wednesday I was better until I did the maneuver at night and I was dealing with moving slowly to avoid the vertigo. On Thursday I saw my doctor who gave me an antihistamine and that helps but makes me sleepy. I think it's supposed to go away on it's own after another week or so. But it will probably happen again in the future. It's less scary now, in fact I had an episode at work today and I dealt with it ( I had not taken the antihistamine ). Originally, I thought it was related to a bike crash I had a week prior to the episode, but the doctor in Iceland and my doctor think it isn't. It just happens to people. I was wearing a helmet, of course, and I'm glad I was. I saw stars for a split second and I think that if I was not wearing a helmet that I would have been far worse off. One issue, supposedly, with doing the maneuver at home is that people do it wrong. I can see that, it's confusing. So I ordered a thing, like a guide, to help help you do it correctly, it's called dizzyfix. i thought of going to an ENT but I'm not sure if I need that, the literature says that regular doctors can diagnose it. Any experiences with BPPV?
