Hi Paul,
Sorry I'm a little late scoming to this thread but welcome to this forum. As you can see, the people here are ready and willing to help in whatever way we can. I have to agree with every one. The symptoms of an AN can waver or come and go, at least in severity. My hearing has gone up and down a couple of times and been documented by auditiograms, and the tinnitius in my ear changes with the weather, allergies and the level of stress I'm feeling on a particular day. Although I do not have claustrophobia, I reqeusted an open MRI because I was feeling anxious about being closed in. Maybe this type of MRI, along with some Valaium or something would help you. Wishing you the best of luck. I hope you dont' have an AN as it is a lousy diagnosis, but if you do, this is a great place to be for support, information and venting when you need to. We are here to support you in whatever way we can.
