ActionSportsWA said..Hi Zib,
I experienced what you are talking about. I took a hard hit in a crashed kiteloop where I slapped my head pretty hard. Everthing seemed ok after the crash, but that night I felt a bit of Vertigo when I went to bed. I managed it but then when tilting my head next morning, the room spun and I fell over. It's pretty scary.
I did a little Googling and through a process of elimination self diagniosed a condition called "Benign Positional Vertigo". This is where a small piece of calcium is dislodged from the bones in your inner easr and then can move around inside your ear. When you lay down, the piece moves to a part of the ear and triggers the little sensing hairs telling the body you are upright, when you aren't or vice versa. It creates the vertigo and acute dizziness, which can make you feel sick and lose balance badly.
I'd look at getting a second opinion from a doc, but there aren't too many things that can bring on vertigo all of a sudden. Perhaps you had a fall whilst learning to foil?
Unfortunately, BPV is not really treatable, you just have to wait for the little fragment to find a spot to stop drifting around in your ear. It does go away but may take a few weeks to a month or two.
Hope this helps and I feel for you, I'ts quite a horrible problem.

Thanks for your input. DM your experience sounds similar to mine in that I had a major head slap coming off the foil in April just before my first episode. I've had two episodes of extreme dizziness like yours (world spinning crazily followed by vomiting). Both lasted several hours, but have been followed by weeks of feeling like the world is swaying and a fair bit of nausea too.
Psycho Jo, the longer term feeling I've had is similar to yours, that feeling of being on a boat even when you've come off it.
I initially had the problem diagnosed as BPPV and have tried a whole lot of maneuvers for varying kinds of BPPV (Epply, Barrel role etc.). It is unusual for BPPV to last more than a month and from what I understand it usually responds to the maneuvers I tried.
The second time it happened (3 months after the first), I got my wife to take some video of my eyes which showed a kind of eye movement called nystygmus (horizontal geotrophic), that my vestibular physio and Ear Nose and Throat specialist agreed was likely horizontal BPPV.
The puzzling thing for me is that it's hung around and that it may be made worse by the motion of foiling. Neither my ENT of vestibular physio seem to be able to explain with any clarity why this might happen. Nothing I've read says that exposure to movement is contra-indicated for the other conditions it's likely to be, that is Meniere's, labyrinthitis and vestibular neuritis. I have heard that Meniere's can cause hearing loss over time which I must say scares me a bit, esp. given the increased level of tinnitus I've experienced since it happened.
The ongoing feeling of being at sea, my desire to continue foiling and the lack of clarity that I've got from professionals made me think it would be worth me checking to see if it's a function of foiling - and where better to ask that SB!
