That must have been bad to hear

Stop

Not sure how if the trip was based around scuba diving

If you're at a place where you can scuba dive, you can probably do other things too.

I don't condone this so don't shoot me if someone does it and fucks their ear up worse, but I've been in a situation like this and I just used those weird orange clay - like earplugs and I was fine. Again, don't blame me if you do it, just saying an experience I had.

Those are fine for swimming pools and the like, but you would probably seriously fuck yourself up if you tried that scuba diving.

Ear plugs don't work for diving unfortunately. The ears need to be clear to equalize. OP could take some meds to allow diving but it could be dangerous and lead to permanent damage.

She probably can't/shouldn't clear her ears, making scuba diving impossible even with earplugs.

Meds are highly unrecommended for diving though, which can wear off during the dive and cause over expansion of the lungs

First hing I was straight when I was getting certified was that if you had an issue that required medication, don't risk seriously hurting yourself or dying.
