I've really got nothing to lose at this point.
You don't know that. If you already have hearing issues, you know things can change from one day to another, and that your hearing can change for apparently no reason out of the blue.
For me health conditions fall in two categories:
1 - The doctor lists the treatment options or surgeries available, and can give statistics of recovery rates, side effects and other risks. The doctor is familiar what the health problem at hand (the best example, cancer).
2 - The doctor can only provide vague information, does not want to be compromised saying anything wrong. The doctor has basically no idea about your condition, due to (i) lack of experience and / or (ii) the condition being very uncommon; and / or (iii) there are no known treatments or standard treatments or surgeries for it.
Category 1) is usually more scary at the beginning, till you hear the treatment options and gather all the information. It may be in some cases lethal too, but at least there is decent research and available surgeries and treatments. It is the beaten track.
Hyperacusis, tinnitus and other rare hearing disorders fall in category 2). That's why it is best to be cautious.
I say this because a doctor offered me a "cutting edge surgery" and it turned out that this ENT had only performed it 10 times in his life, with mixed results, maybe 3 improved, 3 worsened and 4 stayed more or less the same (but with an ear muscle cut).
A surgeon performs certain surgeries several times a week. So if you ask and this is really experimental, be cautious. For me it would be a no no...
