I had SHL about 4 years ago. Similar experience in Urgent Care where it was diagnosed as blocked eustatcion tube. When I was seen by ENT within two weeks and put on steroids he was very upset with this diagnoses and said all medical personnel should recognize this as a sensineural loss. I am now right eared and do reasonably well with an Oticon cross where I can manipulate sound from my IPhone. From my experience and regular visits with an Audiologists I have been fit with the best device available. It’s a handicap but I remind friends and others that I am right-eared and need to sit in best position. In groups it is still hard and I will ask friends to interpret info for me that I’ve not heard. I’m 89, very fit and I can live with this.
