I suspect that my hearing loss may have been caused by a "mycin" antibiotic. Because it is a relatively mild loss, it wasn't like a dramatic sudden loss that a person would notice. And now that you mention advil, I was taking that at the same time! This was for a tooth implant.
At the same time that this was going on, things were very stressful, taking care of a family member in home hospice, so a change in my hearing was not at the forefront. With all the stress other things were going on, like getting little sleep, etc.
This brings up another point. People may say that they have a hereditary hearing loss because grandma and mom and now daughter have it. But who's to say that the hereditary part is not a sensitivity to one or more drugs that are ototoxic. I wonder if this has ever been studied, or even considered.
