Hi, I have good news, my AN remains stable at a bit less than 2MM. See my signature for more info. My sister had a 3MM AN (yes 3MM AN) that caused disabling balance symptoms and I had some balance issues when mine edged over 2MM. I don't think too much about it now. The only thing that I have kept doing is minimizing dental xrays. I have done bitewings in the past year, but I'm not doing the panoramic. I can't prove anything but my AN edged over 2MM a bit after having panoramic in 2011. And my sister checked her dental records and her AN symptoms increased after a panoramic, then they found her AN. Again we can't prove anything. Could be a coincidence. As for my tinnitus, it's still here, I just live with it, it could be worse.
