My symptoms? The same as yours. I went to the local Christian Clinic because I don't have insurance and I've had these issues for ten years (I'm 28 now). They sent me to the ENT. After doing tests, he found that I had nerve damage hearing loss (and another form of hearing loss...), unilateral hearing loss and not to mention the pulsatile tinnitus and the typical tinnitus. What I didn't tell him because I didn't think it was related, were my horrible bouts of balance issues, migraines, facial pain, etc. But anyway. He immediately ordered me an MRI with contrast to see what is going on. He told me that I may POSSIBLY have an Acoustic Neuroma and in his words, "We just need to rule things out. Or in this case, rule in..." So I hope he's wrong. But oddly enough, ANY kind of a diagnosis would be nice at this point. After having this for ten years, it would be great to have some answers. So don't fret. MRIs are normal in this situation. They just need to know what they're dealing with. Both of our scans will hopefully come up clean!
