Hi snoopy. Ooh good luck with yours too and hope it is not an AN. My tinnitus changes from the hissing to a high pitch squeal to a loud dinner bell. Everything goes dead quiet in my ear before the dinner bell one - bit deaf then it starts.
I only get it in one ear - my right ear - this is the ear that I couldn't hear a thing with during tuning fork test. Do you all get it in one or both?
I have read on here about noisy backgrounds too and I have noticed that I find people hard to understand in this kind of environment but forgot to mention it to ENT.
I had an appointment for my son at a hospital, and my son was on the floor to my right crashing with toys, and the dr was in front to my left - he must have thought me rude as I kept saying 'pardon' or 'sorry say that again'! But I found it extremely difficult to make out a word he was saying.
Virtual hugs and best wishes for you appointment next Tuesday.
Lou
