I do not know real medical answers to this question. However I have some out-there ideas which could be tried in a way with low risk of making things worse, and some small chance of making things better.
First the worst idea -- labyrinthitis is commonly diagnosed by MRI. It's not cheap -- probably costs a couple thousand bucks -- but you can get an elective MRI of your head if you really want to see what's going on in there. That's not a great suggestion for your case because you're looking for cheap. But if you get imaging on your own and it shows abnormalities, it could be a good lever for demanding that doctors take you seriously.
Second, consider simulating fever. Some bacteria which like normal body temps stop working right at higher temps that are still low enough not to damage the human. If you have no other contraindications to spending as long as you can tolerate in a sauna as frequently as you can for awhile, it could be worth a try. Just be careful to know the signs that you're getting other harm from excess heat, and cut back if you notice them.
Third, have you noticed any change in symptoms when taking antihistamines for other reasons? I agree that bacterial infection is the likeliest cause, but there's some chance that inflammation mimicking infection can be due to inappropriate immune response to stimuli that would be harmless otherwise. If you're not already on antihistamines for allergies and you have no known reactions to them, it could be a good data point to determine whether OTCs like cetirizine make any difference in subjective symptoms.
Fourth and perhaps silliest, have you tried reframing the "getting doctors to take this problem seriously" as a social engineering challenge, and prompted Claude (preferably Opus) to strategize with you for how to tell the truth from the specific angle that causes medical professionals to pay attention? You shouldn't have to do this, but the medical system is a mess, and roleplaying your doctor conversations with a bot who can highlight anything you say that decreases your credibility from a health care provider's perspective may help you change your interactions with them in a way that changes the outcomes.

Ha, I've been trying to get my head scanned for four years. Haven't even come close to getting anyone to take me that seriously. Thank you, though.

. . . Huh, that is a new one to me, thanks! I've been hanging out in the heat recently, so that's convenient. I'll see if it improves anything.

I'm actually taking certrizine, too, because I was pr...
For amusement, I threw the contents of your google doc at Opus and asked it for questions from the perspective of complimentary medicine. Below I have cherry-picked the ones I found interesting:
I do not have great personal interest in the answers to these, but reflecting on them might highlight relevant patterns to add to your collection of documentation on the condition.
[ edit: I have gotten an ear infection diagnosis and a prescription for antibiotics as of 26 June 2025, [ see comment ] edit 2: as of 5 July 2025, I now think this is probably actually cancer, [ see Tweet ] ]
I have what I think is a chronic inner ear infection. Since March of 2021, I've had subjective obstructive Eustachian tube dysfunction in my right ear, as well as oculomotor problems that as far as I can tell must be caused by some kind of inflammation in my semicircular canals. [ The vestibular problem was confirmed by a videonystagmography, but I moved cities before I could follow up with the ENT who ordered the test. ]
[ Best photo I have left of my VNG results, from June of 2024. The red scatterplots show my labyrinths' response to warm water, blue cold. The purple highlights [ drawn by me after the tester's description ] show where my vestibular heat reflex should be; the red parts of the scatterplot show that at the time my left oculomotor reflex was OK but my right was deficient. ]
[ illustration of how the 2 oculomotor reflexes of each eye rely differentially on input from the semicircular canals of each ear, which can be tested with a caloric reflex test [ part of my VNG ] -- the rapid nystagmus to the right side is simulated by application of warm water to the right eardrum, while the slow nystagmus to the left side is simulated by application of cold water to the right eardrum ]
In July of 2024 the problem spread to my left ear. I've gone to about 8 medical professionals about it, and they've consistently prescribed Flonase/Nasacort and otherwise refused to treat it.
The Flonase/Nasacort does anything [ Nasacort works better ], but since March of 2025 [ when the dizziness had gotten really bad and I decided I'd Try Anything ] I've found that eating 3-4 cloves of strong garlic a day, plus Nasacort, works vastly better than that.
Since garlic is supposed to be an antibiotic as well as an anti-inflammatory agent, the garlic working so well [ plus reading up on the common causes of ETD that has my symptom profile ] made me suspect it was an infection. I tried ordering ofloxacin from TelyRx and it seemed to help a little but didn't end up curing the problem, and it rebounded when I ran out of ofloxacin. I'd been worried this would happen. Unfortunately ofloxacin is centrally for when your eardrums are perforated, so the solution can actually penetrate into the inner ear cavity. My eardrums aren't perforated, and actually look normal to otoscopy most of the time, which is part of why I can't get treated. I tried taking about 5 leftover doses of very-high-dose amoxicillin and that seemed to help even more but frustratingly I only had a few doses and can't get more [ the course of amoxicillin was about 20 pills ].
I would write off the apparent partial effectiveness of antibiotics as placebo, especially given that I've seen 8 doctors and none has brought up the possibility of an infection. But this spring, I got a fairly bad bacterial skin infection [ a coworker said it looked like I'd fallen off a bike ]. I know it was bacterial because it responded very slowly to copious amounts of Neosporin patiently, meticulously applied over the course of several weeks. In the middle of that, hoping to get something stronger that would work faster, I saw a doctor -- who was overwhelmingly confident it looked fungal, and prescribed antifungals. I thought "I've had fungal infections before, and it doesn't really look like that; also, the Neosporin is working really slowly and I'm having to use a lot, but it does appear to be working". I didn't take the antifungals and kept using the Neosporin; a week or so later the infection was gone. That shifted my priors both about [1] how good doctors are at clocking baterial infections, and [2] how patient one may have to be with antibiotics.
I've thought about doing self-myringotomy in the hopes that giving the fluid an opportunity to drain will cure me; since realizing some of the inflammation must actually be in my labyrinth, to be causing the balance problem, I'm somewhat glad I didn't try this -- at least not without having some ofloxacin on hand -- because I doubt that draining alone would solve a labyrinth infection.
I tried using diluted garlic juice as a nasal spray a couple times in May [ your Eustachian tubes connect to your the upper parts of your nasal cavity ]. That seemed to work better than just eating the garlic, but I stopped for fear that the sugar from the garlic juice would sit in my sinuses and cause worse problems.
IIRC I was prescribed a less-than-strong oral antibiotic when the problem started in 2021, but I don't remember for sure, and I definitely don't remember if I finished the course. If I did take one, I know it didn't do anything perceptible. That's part of why I've been hesitant to expend marginal effort obtaining less-than-strong oral antibiotics. If I currently had the money, I'd try ordering strong oral antibiotics from an online pharmacy now; unfortunately, I don't.
Other than garlic, are there any ways known to LessWrongers of killing bacteria in your inner ears which don't require a prescription or much money?
