I guess we all think this when we get some kind of disease. I attribute my Meniers to some hard blows to my head whith riding accidents. But I will never know for sure.
My crisis come about every 6 months but they are very nasty and horrible.
I live with a constant fear that they might happen anywhere or anytime.
But I try not to let this ruin any plans in my life. Someday soon they will find the cure for it, I am sure.
