Not to discourage you but the doctor may not help as much as you can. If they stray from normal diagnoses and protocol, they can prescribe something like corticosteroidal drops for the ear to stop inflammatory damage.
Most important is you don't eat anything ototoxic for the next month. The delicate repair procedure will be compromised and may only resume at 90% of what it could be with each exposure to things like excessive carbs (stop the coca cola and refined sugar) excessive sodium/glutamate (no crap foods), antibiotics in poultry, etc. Get decent good protein. I don't mean meat, the same percentage protein exists in whole wheat, brown rice and anything raw and unrefined. In the case you eat lots of crap now, fix that at least for a little while. While I don't know how big of a difference this makes, flavinoids (from fruit and other plants) are sold as something called Lipoflav or similar to eliminate tinnitus (which is according to another study actually the brain incorrectly compensating for slight hearing damage) as well as another study saying flavinoids essentially cure schizophrenia and horrible physical degenerations of the brain. More raw fruits and veg will never hurt anyways.
You are what you eat and breathe. That fully holds true, including the little hairs and structure of the cochlea.
Be confident there will be no lasting damage. In the worst possible case, the brain uses data from the other ear, and methods we don't yet understand to reconstruct the data that should be there. Perceptively, unless you're listening to test tones, you will never notice.
The fact that it wasn't high frequency spared you the greatest bit. HF pretty much vibrates a small number of sensitive filaments to oblivion, and they don't work right again. Low frequency would more or less be like strong barometric changes happening too rapidly for the blood supply to the area to adjust to. Basically, the hairs and tube all gently got compressed and sucked on, instead of select few ripped to shreds. That would explain a dull ache, rather than a very strong tinnitus akin to going to a concert drunk (goddam never drink alcohol at a floor concert. The thinning effect suppresses the ears ability to dull the sound as much. Only time I did left a week of tinnitus...)
Ask the doctor for everything they can to naturally assist in damage repair. The reason I am enthusiastic here is I had/have interest in lasers and lights before pro audio (music came first
and after a 200 mW 100 millisecond exposure conveniently right in the macula, I was left with a spot smack dab in the center of the good eye, the size of the word "of" at a normal distance from the screen. Pretty much, effective vision acuity was cut five times. I had to come too close to street signs to make out what they said, too little room to change even two lanes to make the turn. The optometrist was understanding and referred me to an opthamologist appt within a few days. He prescribed me steroidal drops that he hoped would make it to the retina when applied in large amounts (4 drops at once, but only once a day) which would forcibly stop inflammation, and resulting damage/attack by the immune system. Furthermore, he had a bunch of trial packs of a vitamin supplement very high in vitamin A equivalents as beta-carotene, and other helpful things, originally for age-related macular degeneration. He gave me a huge handful of these trial packs, it took me a month to finish them. I now have no resulting little spot left, 4 years later, while a year after I would actually notice a dot the size of a period missing. This includes very low light (like normally heavily shaded outdoor areas, but at night too) which I expected to work a bit worse, having some but possibly only a fraction of the functional cones/rods left, and artificially boosted by the brain to look like nothing was deficient.
Essentially, attitude towards it is the most important part, and you will pull through with no deficiency. Just don't abuse the repair process, the body has evolved forever or has been made to be this resilient.
Unfortunately in the pursuit of pro audio, we will never find extreme-level limiting circuitry added onto these amps. What happens when an amp fails and a cap discharges right into the driver of an extremely well fitting and high-excursion headphone? Or simply something running at 1/20 the volume max has a short across the resistor/pot limiting it there? Especially with some noisy metal or something. While laser forums have constant discussion, there will never be sound protectors as far as audio goes. At least it is much harder to have this happen...
Edit:
Along the lines of a following post, any vitamins, mostly fat-solubles will help a lot. A, D, E and K, and C is cheap and easy to get in large amounts. Avoid artificially-sweetened C tablets, that crap (sucralose, Acesulfame-potassium, sodium cyclamate) will neutralize half the efficacy of it. Take with food.
