.First of all, allow me to congratulate you on your concise, full and relevant post, it did indeed help immensely.
I presume that you have had blood tests, X-Rays and audiological evaluation and have been assessed by a medically qualified person.
II would also like to know about your occupation as a sound engineer, how noisy and for how long that you have been working in that environment.
You have what is known as Hyperacusis and takes many forms, one of which is pain in the ears following noise exposure.
Damage to the inner ear from ageing or exposure to loud noise is the most common cause. It is not possible to repair the inner ear, but the condition can be managed.
People who suffer from reduced tolerance to sound hyperacusis) often find ordinary noises seem to be too loud, while loud noises can cause discomfort and pain. Damage to the inner ear from ageing or exposure to loud noise is the most common cause.
There is usually no cure once noise sensitivity has started, because the common causes are noise damage and ageing damage to the inner ear. It is wise to avoid exposure to noise in the first place. There are disorders of the inner ear, which are treatable, so prompt assessment of the ears may be critical to manage the tolerance.
The most common known causes of sensitivity are exposure to loud noise and ageing.
• There are no objective tests for diagnosing decreased sound tolerance.
• There is usually no cure once noise sensitivity has started. It is wise to avoid exposure to noise in the first place.
• Treatment focuses on insight, reassurance and protection of the ears.
Sorry that this is a bit rambling, but it is not and easy topic to describe, but you can Google the subject or some AB member will give you some websites.
I see no point in consulting a Neurologist.
