right ear hum

Dear Doctor,
When I was in college, nineteen years ago, I was sick a lot. Many sinus infections and then an ear infection that sent me to the emergency room in agony. After that I developed a hum in my right ear that never went away. (I have to sleep with a white noise machine) Sometimes, it is worse than ther times, like right now. I had it checked out in college and the doctor removed a lot of wax from my ear, but the humming never went away. The humming sounds like a car in the distance.
I finally need to take care of this because it is driving me mad. Where do I begin? I don't have a lot of time to to wait in doctors offices and take tests. Please help me
Thank you.
