You are right it is something to think about. I always just thought or rather wanted to believe if I don't need a hearing aid for the right ear that means/qualify of the two of them it's the normal or Good ear, I was told in definite terms yesterday that's not the case. So in my financial mind I'm wondering if I should do it. The other thought is do I really want to be stuck without it if and when it fluctuates again and struggle.
That is something you will have to really think hard about .. sounds like you have already made up your mind, so go for it
