In my right ear, I feel pain, mostly at night when I am sleeping. I feel no pain when I am calm but when I hiccup, swallow hard, yawn, or anything similar I feel bad pain inside my right ear and it wakes me up. It happens several times at night, and a couple hours after I wake up. And Minimal but still happens later. It may or may not be because I was using earplugs a week ago and I feel maybe it's infected? but not sure. It has been 1 week

I am in vacation in a tribal mountain village in Vietnam, the doctors even in Hanoi, the capital don't know much English and if they do they prescribe without really knowing or caring about the real cause. They just want money. There are pharmacies here, I just don't know what to buy. Please help
