Krystal, I assume you are seeing a ENT specialist... if not, I would recommend you do so.
I'm not a doctor either, but I can relay to you how my testing came about... Over this past summer, I noticed a profound hearing loss coming about in my left ear along with very loud ringing and periods of dizziness and unsteadiness. Then, my right ear started ringing. I finally called a doctor to get it checked out.
First, I saw an ENT specialist who conducted an audiogram test to confirm my hearing loss (I had hearing loss in both ears, but really bad in my left ear). Once this came back showning my left ear had hearing loss, he ordered an ECOG test and an ABR test. My ABR test came back abnormal for my left ear, thus an MRI was ordered next. I was found to not have an AN on my MRI, but my ECOG test showed I have Meniere's disease which was causing my problems... and I'm getting treated for it now.
Good luck.
