Hi Nini,
You are not alone! In January, I had sudden hearing loss in one ear, roaring tinnitus and many other symptoms (head tingling and tremors, head aches, aural fullness and occasional ear pain, and feeling of imbalance when walking down stairs) - I have had 2 MRI's - with contrast and one MRA. so far, nothing has come up to show the cause. Like you, I am so bothered by the tinnitus. I think it is actually causing my head tingling and tremors. I am sure the worry about what all of the other symptoms are caused by are making the tinnitus harder to deal with. My sleep is horrible - as I wake up several times a night from the noise in my ears. I am going for a 3rd opinion on Friday and bringing the MRI disc with me. This doctor plans on looking at the actual film - unlike many of the other doctors I have seen, who only looked at the report. Anyhow, I totally understand your anxiety. I recently started a new job - and it is so hard to interact naturally with my coworkers while hearing all of these strange sounds in my head, and struggling to hear conversation at the same time. I hope you will take comfort in knowing that I understand what you are experiencing. Please keep us posted on how things turn out. It may be that we both have an atypical form of Meniere's Disease (without the disequilibrium/dizzies). Best wishes and sending prayers your way...
