Yesterday I diagnosed and treated my own posterior canal BPPV (by far the most common form).
I’m a PT. I treated it using the Epley Maneuver.
This animation shows the technique I used and illustrates the rationale clearly: https://www.youtube.com/watch?v=9SLm76jQg3g
This video with a live patient is also helpful: https://www.youtube.com/watch?v=K4S4CbuN6QA
The vertigo was occurring when I turned to the right in bed, so I did the same maneuvers as shown in the 2 videos. (If vertigo had been occurring when I turned to the left in bed, I would have reversed the direction of the maneuver, i.e. begin to the left and then move to the right.)
My H was at work so I did this alone, but I recommend having someone there to support your head, or to help you change position. I have read that some people feel quite dizzy/panicked for a few moments when they sit up at the end; having someone to stabilize you if needed is safer than not having anyone there.
As one gets into the first head back and turned position, vertigo occurs. It’s quite unpleasant but short-lived; it stops in about 30 seconds, when the otolith reaches the lowest point that gravity pulls it to in the canal, which is why they tell you to wait that long-- but don’t just go by a timer; go by when the vertigo ceases. When it ceases, that’s the time to switch to the next position, which will again trigger vertigo, as will each subsequent position change. Each turn moves the otolith to the next position. Think of it as rounding the bases. When you finally sit up, the otolith reaches home plate!
For the rest of the day, avoid putting your head down. I actually put on a soft cervical collar as a reminder.
For the first night, sleep with your head a bit elevated.
I did this yesterday. Today: no more symptoms. But something like 20% of people have to repeat it. And it can recur, in the future, and you can re-treat it.
BPPV is positional vertigo-- it does not occur in every position. It is paroxysmal– it is not constant. I just want to emphasize that not all vertigo is BPPV and therefore not all will respond to these kinds of maneuvers.
Mine was posterior canal BPPV. There is also lateral canal BPPV and anterior canal BPPV, and the maneuvers for those are different.
