Hello to all!
Some of these questions may seem repetitive but would like to know.
This is going on my second week of having bppv,had it several other times this year but could usually treat it on my own with the dizzy fix. This time is a little different in the fact that it won't go away. Doing basically the epley every day and sometimes at least three times a day. For a period last week nothing was moving (and as a result I felt like I was on a boat and mild head aches )then one day I felt the vertigo while doing the exercises. Kept doing them daily thought it would clear up. My right ear is affected went and had a hearing test fine went to an ent he said I had bppv did the epley and he asked me to demonstrate the hat(dizzy fix) nothing really changes .still get the eyes moving around doing the exercise. Anyway I was reading on this forum with someone else that perhaps its possible to get the particles in the horizontal canal so try doing the log roll if the epley isn't giving relief? Feel a little vertigo when laying on right side and stomach. Does that mean it is in the horizontal canal to along with the poster?
Anyway feeing frustrated as I'm sure everyone else has too. Just weird because befor it went away with the exercises how many rocks are in there.? Any advice on techniques or if perhaps its in another canal?
Thank you
