I'm not sure it works like that really.
Anyway I wouldn't worry about it, worrying if your Tinnitus will be worse in 30-40 years, it's the same as if you were worrying if you'll get cancer in 40 years or anything of the sorts.
While this forum is great and all there's people here having a hard time, and what it can do (at the very least for panicky obsessive idiots like me) is give you the idea that Tinnitus will 100% (get worse,make you depressed,never go,never improve and so on and so on) when in reality loads of people have Tinnitus and loads of people don't have it increase.
They get it, it stays (or in some cases goes even after a long time) and in the end they don't care about it and they lead on with their happy lives.
I really don't see the point of your worrying yourself about it no one can predict the future.
In 10-15 years there will probably be treatments if not cures for some cases of Tinnitus.
How did you get yours? there's research going on into hair cell regeneration and scientists believe we will be able to regrow hair cells in humans as a treatment for loss of hearing in 10 years time.
There's also the trials, of which the most promising to me is the N-something thing I can't remember where they give you something that actually gives hair cells the ability to regrow.
Actually, the human ear can regrow hair cells but when the hair cells are damaged high amounts of potasium? I believe are released therefore blocking the hair cells from regenerating, what the N thing does is it represses the potasium giving hair cells the room to regenerate.
All in all instead of focusing on how yours might get higher in the future which probably won't be the case think of how there will be treatments for hearing loss in the future one will most likely not happen while the other is already being worked on.
Hope this helps
