Loopy, I was sent first to the physio-- no good,
Then audiology[ this is in Scotland] where first I had my hearing tested, its not that good, but not hearing aid worthy just yet in my opinion. She then did the Epley, and a repeat next week.
Googling I also found a radio prog, medical I think from St Thomas's London, which was pretty comprehensive on BPPV. There is lots of 'Merican info, including one site which willsell you a contraption which you wear on your head with ping pong, or similar balls. its supposed to work by trying to get the balls aligned, thus rearranging the crystals.
Hope you have success in finding a reputable practitioner.
