What’s your age in decades (20 - 30, 30 - 40, 40 - 50, 50 - 60)? I am not a physician, and don’t have this condition, but I do know some family and friends who have it. However, I would have your condition checked out by a dr to make sure it is not some other underlying cause like high blood pressure or some neurological deterioration. It could be age related depending on your age, and there are supplements one can take to soften or eliminate the ringing. There also prescription meds your dr can prescribe.
This must be annoying as ****. Please state some more info I’m asking above, and I’ll give you my 2 cents worth (I’ll do some research for you). Hope it goes away.
