Yes, no fun. Had that done years ago. Also a head gear put on, had you turn your head from one side to the other. My left was bad..eyes going crazy. I now know when I have a loose crystal. I go into my bedroom to do the epley. Thank goodness it works. Doesn't take care of the Vestibular part, but I'm better. When I'm ending up on the floor I'm pretty sure I have a loose crystal. Takes a while for things to settle down after that. Have they done the long bar with red letters and words flashing across while you sit back and watch? That no fun either.
