@ed140 Hi. I posted this a week ago for someone else, but I will repeat it for you as your loss sounds like my wife's. She woke up one morning 2 years ago with no hearing in one ear. I got her into my ENT the same day and he prescribed steroids like yours did. But he also had her get an MRI, which showed that she had an acoustic neuroma (non-cancerous tumor) pressing against her hearing nerve. It was small. Within a week of drugs, her hearing was back to normal and she has been normal for 2 years. However, even though acoustic neuroma's are typically slow growing, we go back for follow up MRI's each year to make sure it isn't getting too large. She might still need to get it surgically removed in the future if it grows too big. Hope this helps. I would get an MRI if I were in your shoes so you could confirm what it is. Good luck.
