### Patient: Doctor, I've been experiencing continuous ringing in my ears for the past few weeks. I'm quite worried about it. 
### Doctor: I see. Well, we need to do a few tests to determine the cause of your tinnitus. I recommend an ophthalmologic and otologic diagnosis and treatment for your ears. In addition, we need to conduct a Magnetic Resonance Imaging (MRI) test. It would also be helpful to perform other diagnostic procedures on your ear, nose, mouth, and throat. We may also need to do other therapeutic ear procedures or other physical therapy and rehabilitation if required. And finally, we may need to do other diagnostic and therapeutic nervous system procedures as well.
