Very poor english translation. It should say , "do you have an earache?" Or " do you have a pain in your ear"
Perhaps... the grammar is correct and I could easily imagine my doctor asking me if I have ear pain. That, however, would certainly not be the common expression.
Is ухо no longer accepted? In a Ukrainian text book I have from the 1990s that is how ear is spelled.
In English I would say, "Does your ear hurt?"
I concur with what has already been stated by the other Duolingo users. In (American) English, we say "Do you have an earache?" OR "Do you have pain in your ear?"
You can say, my boss is a pain, however.
