> If you ask your doctor, they'll tell you never to put anything in your ear that's smaller than your elbow
I'm pretty sure doctors in general are not opposed to the use of earplugs. Doctors don't want you putting things like Q-Tips into your ears, because it's really easy to irritate the ear canal or worse accidentally puncture your ear drum. Ear plugs don't carry much risk (no chance of hitting the ear drum unless you're shoving them in with a stick, and should be gentle enough on the ear canal), and they are a very good idea if you're going to be exposed to loud noises. Good ear plugs can block as much noise as good earmuffs.
Doctors themselves (or their technicians) will put earplugs into your ears if they need to block noise, e.g., for an MRI or a hearing test.
