I heard there may be cures for tinnitis now, does anyone know anything about it?

My mother had this from an injury to her ear for 50 years. I have had this in both ears for the past 35 years. I've tried everythng. If you find a cure, let me know. Thanks.

It depends on the cause but if anything would 'cure' it the 'remedies' are
Cut out excess salt, alcohol, chocolate, cheese.
Eat a diet rich in vitamins A, B complex, magnesium, protein, choline, zinc,
