### Patient: Doctor, I have been having a ringing in my ear for a few days now and my hearing seems to be diminished. I also have a cough and a fever.
### Doctor: Based on your symptoms, it seems like you may have mastoiditis, which is an infection of the mastoid bone behind the ear. It can cause ringing in the ear, hearing loss, cough, and fever. I would like to examine you to confirm the diagnosis and determine the best course of treatment.
