Hello Jack,
You mentioned going to hearing clinics with no helpful results. Hearing clinics vary so much in ability to assist. It depends on the education and experience of the staff- and that varies widely from a week’s training all the way to a medical degree, residency & board certification.
Perhaps a medical professional who can examine you from the “ears and brain” perspective will be of more benefit for you.
If I may, I’d like to respectfully suggest starting with an otolaryngologist. She or he will do a thorough examination and, if necessary, refer you to a trusted audiologist, otologist or neurotologist depending on your situation.
For a real-life example, much of my hearing challenge (a lot since birth) has nothing to do with the ears. And the tinnitus I have is 100% neurological. For this, a generic hearing clinic would not be of benefit.
The most important thing is to continue to pursue a solution for your hearing challenges. Over time, if not addressed, hearing troubles can result in nerves failing you. They simply give up.
The sooner you can address this and start the journey to happy hearing, the quicker any hearing assistive device can provide benefits to you. (The brain takes time to adapt. The sooner it starts learning to hear and understand newly regained sounds, the quicker you will be enjoying sounds once again.)
Please keep us posted on your journey. You will love being able to hear and understand once again!
Paul
