Please do not pay any attention to what you have been told by your ENT doctor regarding tinnitus. He or She knows about the anatomy of the Ear, Nose and Throat and able to treat most underlying medical problems associated with them, either surgically or medically as this is their area of expertise. However, Tinnitus is an entirely different matter as most ENT doctors have never experienced it and therefore, know absolutely nothing about how it affects a person's mental and emotional wellbeing. Granted, they may have a lot of experience consulting with tinnitus patients but this does not make them tinnitus specialists.
I have been saying this for quite some time and evidence of this is what you have been told by your doctor. Tinnitus is a very common condition and many people habituate to it and carry on to lead a fulfilling life doing everything that they want to. Although it can be severe and debilitating for some people, it is not quite the doom and gloom that your ENT doctor portrays. With treatment a lot can be achieved. Unfortunately some people do not know as I and others do who are experienced with tinnitus, that ENT doctors are physicians not tinnitus experts.
No amount of medical qualifications and Phds will make them an expert in this condition for the reasons I've mentioned above. Too often they are given a reverence that they do not deserve and have this purely because they are medically qualified, but have no personal experience of living with tinnitus. Those that do probably have it mild nothing like what people experience in this forum. Therefore they still cannot understand how it can affect a person when it is severe.
Hearing Therapists and Audiologists that specialise in Tinnitus and Hyperacusis treatment and management, have more understanding about these conditions. Not surprisingly a lot of them have tinnitus and therefore, able to empathise with a tinnitus patient especially with counselling, which can help them to habituate.
