@Dizzylady25, I wholeheartedly agree with Helen.
Try, try, try not to overthink this.
I did a caloric test at my ENT office about 3 months after MAV struck (did not have a diagnosis yet). The caloric testing showed I had 79% Vestibular loss (nerve damage) on my left side. That’s a huge amount of Vestibular loss!
I trudged on with Vestibular rehabilitation to help retrain the nerves that were still functioning.
After 11 months of hell, I finally saw a Vestibular specialist (Otolaryngologist) like Dr S. I brought along my caloric results and of course expected him to tell me the same as what I had heard before. However, he said “I can see how the results were mis-read but you definitively have Vestibular Migraine”. So, to the end point: I have no idea if I do or do not quite honestly. I do know that MAV can skew the typical testing, can show white matter lesions, can present with nystagmus… all of the things that would lead an uninformed Dr down the path of other awful conditions. Quite the little devil MAV is!
Don’t panic, leave your care in the hands of Dr S who is trained to identify the nuances of this condition.
