I’ve never been diagnosed with tinnitus, but I’ve been living with it for decades. I mostly have a low-level, staticky whine, but sometimes I’ll have attacks that are high-pitched, loud, and painful. I will also rarely have bouts where my hearing is muffled and definitely feels like someone is behind you blocking ambient sounds. The in front of you part is probably blocked out by our eyes showing nothing there.
I likely had undiagnosed depression for decades before I got treatment, from a GP, no less, after being dismissed by a psychiatrist. If you have concerns about your health, keep trying to get help, as long as you’re able.
