Oh I should add that the only thing this might be is gonorrhea, and with your eustacian tubes being involved, I'd doubt it is.

Most pharyngeal std infections will cause no symptoms, but why not go to an std clinic and get a throat swab done before going to the ENT? You can self pay (if there is a charge) and no one will know.
Google your town, state and std clinics to find one near you.
