I am certain that mine is NOT related to noise trauma. I never listen to music, not even in the car. I love(d) my peace and quiet, and there were no unexpected loud noises near me prior to tinnitus.
In August I lifted a fairly light weight at the gym incorrectly. All the force in lifting went to my head and I was struck with an instant debilitating headache. No history of headaches before that. Long story short, but after seeing a neuro and getting on some meds, the headaches went. I went back to the gym November, but the headaches returned late November. I had daily debilitating atypical migraines. I doctor shopped, and presented to emergency EIGHT times, but I was always turned away because my imaging was normal, and told to take Ibuprofin. (Like I wasn't doing that already). Tinnitus started the week after the late November onset of headaches. Tinnitus went away though, and came back on the 23rd December. Went away a second time, but I have had it 24/7 since the 28th December 2020. The morning it returned for good was after a debilitating headache the night before.
I'd say my tinnitus is neurological damage from the headaches, or the accumulation of Ibuprofen I was taking to control the headaches on top of 2 blood pressure meds.
My hearing tests are normal for my age (42). My tinnitus is in both ears, but it is mainly in my head (which I find far far worse) and I can feel it as well which is unnerving. My head sizzles and vibrates.
