> An audiologist friend told me to go to an ENT physician if not better by 48 hours or the damage could be permanent. Much longer than that and it would be too late to try any of the interventions This seems like poor advice. If there is significant, realistic concern about permanent damage, I'd suggest checking immediately, rather than give it extra time...
It’s often a cost/risk trade off. A lot of things do fix themselves with time and if you default to going right to the doctor every time you’re injured or feel sick it’s going to cost a fortune, unless you have some kind of gold plated insurance. Some things have to be looked at right away, but for some things it’s unnecessary, and it can pay to wait it out. (of course the above reasoning is pretty specific to the US…
The other big issue I have with doctors, I don't know if they are going to prescribe me some bullshit because the real treatment is "you'll get better with time" or the real answer is "there's nothing we can do about that." Or, much worse, something that they believe will help you but is not evidence based. Before you get upset - I once had an MD refer me to a (licensed) physical therapist for craniosacral therapy (complete woo) which billed it to my insurance as something like "physical manipulations."
It's also just how I was raised, when I grew up, my parents would say "we'll see if it gets better," and it always did. When I grew up and starting visiting the doctor for things at the advice of others it didn't improve my health outcomes yet significantly increased my annoyance level.
