Yes, it does sound like it could be lupus related -- but almost anything can be lupus related, there aren't any limitation on where/what in the body it can attack.
It could be an inflamed gland or something like that. I assume it bothers you a bit or you wouldn't have noticed it. Warm salt water gargles, maybe?
