TMD is perhaps THE MOST likely to have positive results, considering its muscular inflammation causing much of the problem and muscular inflammation is one of the few things heavily studied for LT - whereas the cochlea is not.
I started shining my light on my left TMJ out of cruiosity a week or two ago after I had a really bad bout of PET when doing cardio. (It was horrible. I had to stop exercising it was so bad. Every breath was being redirected instantly into my left middle ear). Since then I have had some interesting fluctuations where I can get my ears to sound almost normal again.
Normally since this has all started, I could hum. And everything sounds as if things are transmitting and resonating primarily in the left side of my head. (Much louder than the right side. Even though I have essentially zero low frequency hearing loss in my right side. Maybe a few dB. Nothing severe)Once in a blue moon, things would sound normal ish. But not often.
After this and after I started shining the light on my left TMJ. I have been having a lot of days where the sound almost sounds perfectly even between both sides now. Though it fluctuates a lot at any given moment, and it seems if/when I can pop my left ear/jaw and it will change maybe. Or not. And when it's near perfect, the really bad asymmetry I felt I had in hearing almost seems to go away with it, like 80%.
(I don't know if shining the light in my right ear 3x15mins a week is changing anything either. As I don't have flat enough headphones to do accurate manual audiograms with. The only frequency I can consistently get a SNL with, is at 12.5Khz in my right ear. I've been thinking of going back and paying cash for another Audiogram with additional tests at specific frequencies as well, since I lost my insurance.)
I dont' know if this is coincidental or not.
As for the eyes, I haven't had any flashes. But somedays, when I find the big sweet spot for shining the light in my ear. If it sits there long enough. I start to get a bit light headed/(dizzy?) and in the process my vision is affected like with normal light headedness.
I wondered if this was due to something like the Endolymph Fluid getting heated up or something.
I've been considering buying this light as linked earlier

Just to try a stronger light on my left TMJ maybe and experiment with shining it on other stuff. Maybe the ears, though I wonder if it's too powerful.
