The difference between mild and severe/catastrophic
My partner has tinnitus. He's had it about 2 years. It is a 'slight high pitched ring when it's quiet.' He hears it some night, but not all. His is mild.
I developed mine about 14 months ago - 5ish tones, oscillating, reactive, dysacusis - after illness and losing some hearing. I'd classify it as severe on a good day, possibly catastrophic on the worst.
We were talking yesterday about how much money we would pay to get rid of it. He said at most, he would pay $100 to get rid of his, certainly not more. Meanwhile, I would pay our entire net worth (high 6 figures), including the house and pension, to get rid of mine. He found that hard to believe, buts its the gods honest truth. I'd actually live on the street and start from 0 again to have another shot at life and silence.
I think I've found a new way to classify tinnitus - severity and life impact is based on what you would be willing to give up in order to eliminate it.
