I've had ENT problems basically since birth. As an infant, I had tubes in my ears and had my adenoids removed. As a pre-teen, I had ear infections again that we couldn't afford to treat, so my ear drums ended up bursting and the infection drained, but I've had tinnitus ever since then.
Anyway, when I was 14 or so, I got "walking pneumonia". I ended up getting pneumonia 4 times in 2 years, so my GP sent me to an ENT specialist, they did a cat scan and had a staph infection with polyps in my left maxillary sinus. So at 16, went in for endoscopic nasal surgery where they took my tonsils (which were always oversized, but would swell up when sick to the point it was hard to swallow), lasered open my nasal passages, and cleaned out the infection.
Today, I have problems and have to go in about once a year to have impacted wax removed. I don't put anything in my ears, but my ears already produce a lot of wax and it's also very sticky wax. Compound that with the fact that I also have eczema and the result is wax that doesn't fall out like it's supposed to. I've recently gotten an endoscopic ear wax tool with a spoon that has various tips because insurance never pays for my ear cleaning ($150).
Anyway, I've had mild tinnitus all my life and just live with it. Occasionally, maybe 1-2 times a year, it'll spike to the point of being painful. There's no treatment for tinnitus. Some things can make it worse for some people, like caffeine and nicotine. Neither seems to affect mine.
I don't really find it hard to live with and my hearing is still decent. I got way more and way worse problems than tinnitus, like the schizophrenia with severe negative symptoms (and of course, still no treatments exist for the negative symptoms), permanent [mild] pseudoparkinsonism from prior treatment of the aforementioned schizophrenia that I also can't treat because the medications to treat it could make the schizophrenia worse, severe delayed sleep phase disorder, and a plethora of other annoyances (seborrheic dermatitis, mild dyshidrotic hand eczema, mild hyperhidrosis of hands and feet, poultry meat intolerance, chronic gingivitis, and probably 10 other things I'm forgetting)... so yeah, untreatable tinnitus is not only par for the course for my life, but relatively nothing in the grand scheme of things.
