I have had ringing in the ears for many years, about 5 years ago, I started going deaf in one ear. About 3 years ago, I started having a balance problem. About 2 years ago, I started having major difficulty going up stairs (have to hold on and pull) About 6 months ago, I started having bad acid reflux and the doctors are saying the pain in my ear is from the acid. They have done two MRI s of my head and found nothing. My balance is getting worse constantly and the noise in my left ear is extremely loud. What is wrong with me?
