Me too, had it for the first time a few years ago, saw a consultant who checked me over ( the words Brain Tumour were mentioned) he then did the Epley manoeuvre on me and it worked, he also showed MrOops how to do it as my GP was rubbish at it.
I’ve had it several times since, I try to sleep on the ‘other side’ to the affected ear, but it takes weeks for me to get over it, each time MrOops has to do the Epley manoeuvre until it gets sorted which can take some time to get right, but I end up walking into the door jamb etc as I lose my special awareness for a while.
I still have off days though when I don’t have the full on BPPV but I get wobbly if I turn over quickly in bed or jump up out of bed too quick.
It’s a pain, Rufus over in Oz was a sufferer as well and we used to commiserate with each other.
The only thing that has happened since is that I’ve stopped driving myself on long journeys,’just in case’ as my last attack came out of the blue when I was in the kitchen.
Hope you get over it soon, it’s a horrid thing to have.
