@sjd324 Did your audio or ENT send you for an MRI to rule out an acoustic neuroma? This happened to my wife 2 years ago when I was at the Salt Lake City HLAA convention. My wife woke up that morning and sent me a text to call her ASAP. She said she woke up with loss of hearing in one ear. Fortunately I was surrounded by experts at the convention. I found an ENT who said to immediately get to an ENT for steroids and an MRI. They gave her another drug but I can't remember what it was. By getting on the steroid right away, the inflammation of the neuroma, which had been pushing on her hearing nerve, reduced within several days and she has been fine since. Since her neuroma was small, we just go back every year to see if it has grown much. They are usually slow growing.
