The best thing for you to do is to see a ENT wherever you are staying,but don't get ear tubes! do all you can do first to clear that ear,I also had a infection and after that cleared I was left with fluid behind the ear drums,I never had a balance problems though,but got the tubes,was a big mistake for me,it did leave me with some hearing lost and will have them removed in Aug,that will be one year for me.
