1. "Most tinnitus caused by acoustic trauma fades over time, typically within 6 to 18 months. In many cases, it fades completely."
2. "No matter how loud it seems today or how overwhelming the ear pain, fullness, and sensitivity to noise may feel, it will improve over time."
Those statements lack scientific or statistical evidence, and the rest is entirely opinion or subjective (100%).
Even if some people post and claim that "they improved," it remains subjective and often doesn't make sense. If it's acoustic trauma specifically, our ears might "heal" to some extent, but the degree of healing depends on the severity of the internal damage. The "healing" can only go so far.
My statement that tinnitus doesn't "fade" is subjective, sure—but I know a few people in real life who have tinnitus. At least four people have shared their experiences with me, and none of them have told me it "faded" or improved. In fact, two of them said it got worse. One person mentioned it got somewhat worse, while another—a friend—said it got significantly worse. That friend has since told me, "What you said was true." They were initially skeptical, or maybe just reserved, but they eventually acknowledged my perspective. However, I don't say "I told you so," because my intention was only to help.
It just doesn't make sense to me that tinnitus would "fade." Why would it? There's some kind of damage there. The only "positive" aspect for some people is that it fluctuates. Mine fluctuated too, but ultimately, it got worse.
