Hi Claire,
Oh yes, I had some vestibular therapy done a couple of months ago - as soon as the therapist finished and sat me up, I threw up in her office - she said no one had ever been sick after the treatment in her 10 years...I continued to be VERY, VERY sick for the next 12 hours or so and it was several days til I was back to my "pre-treatment" tolerable vertigo. They told me I might need to come back for another session, but I never did. My vertigo actually did completely go away for a few weeks, but it's back again. I don't plan to try any more therapy for now. I am going to wait til I decide how to treat my AN. I have heard and read, however, that the therapy definitely works for many, many people if you are willing to stick with it.
I took Meclazine years ago when my vertigo first started, but my ENT said I really need to get off of it - I tried some excercises at that time also, but never kept up w/ them. My vertigo eventually became tolerable (brain retrained, perhaps??) and I've just lived w/ it until recently when my AN was discovered and one of the specialists I saw tried the vestibular therapy.
Good luck and hope you feel better soon - let me know how things go. By the way, have you had your AN treated?
Cindy
