I've called it a battle because that is what it feels like. I have a high pitched whistle in my right ear and hyperacusis in my left ear. Every sound in my left ear sounds really loud and as if it is coming via an old short-wave radio. It came out of nowhere and has had a devastating affect on my life.
Lost count of the number of medications. On a positive note. I so sleep well.
I have read that some people have had this for over 20 years. Hoping that someday someone finds a cure
