Correct me if im wrong. But tinnitus doesnt come and go. Its something you have or you dont, and once you have it, its there and will only get worse as more damage accumulates.

I have it, mostly from hunting without ear pro. I dont always notice it, but its always there. Its usually mostly noticeable when im going to bed at night,when scuba diving, or when on a plane and I havent cleared by ears.

OR if/when i have headphones that create a seal in my ear, like the silicon earbuds that create, which is why you can hear yourself chewing/swallowing. Its a main reason i don't wear those types of earphones.

Tinnitus is always there, its permanent. But it just may be noticeable under certain conditions or circumstances.
