Thanks, Ner. Answers to your good questions:

Q: Where on Earth did you find treatment allowing you to narrow down the cause to your cochlear hair cells and inflammation of the cochlea?
A: The attached vestibular tests were done (electrocochleography and otoacoustic emissions) about 6 weeks after my hearing loss started. The audiologist said everything tested normal except for outer hair cells in my left cochlea. That's how I narrowed it down to the hair cells. And since the transtympanic steroid squirt into my inner ear fixed my hearing temporarily, I assumed that meant that I have a pressure or inflammation problem in my cochlea and the hair cells aren't dead yet.

Q: How did they make that determination?
A: From the attached vestibular test results.

Q: Did the timing of the steroids injection (how soon after hearing loss) have anything to do with its success?
A: According to my ENT, the timing of the injection which was about 30 days after onset did not have anything to do with its success.

Q: And what were you reading that pointed toward Delta 8 gummies as a possible solution for it?
A: It is my guess that the perilymph fluid in my cochlea is over-pressured, just based on what I've read online, so I've been doing all things anti-inflammatory: healthy eating, low sodium, more cardio, better sleeping, and trying some anti-inflammatory supplements. And then I randomly remembered that THC is also a good anti-inflammatory so I just tried an ongoing low dose for a few days and then my hearing started improving.

Again, we're all different and nobody knows if my efforts are cause or coincidence, but since I tried a bunch of things, and my hearing is improving, I thought it would be worth sharing my experience.

All the best,
Dan
