Ear problems

Tomorow I have an appointment at the ear doctor to hopefully find out what is causing the non-stop ringing in my left ear. It has been ringing for almost five or six weeks and is really starting to bother me. I looked it up on the web and found something that I do believe it might be and if it is that then it is something I will have to live with but at least hopefully the doctor can help give me ways to minimize the ringing in my ear.
