Hum in one ear

[IGOR.]

At me constant hum (either hissing, or a whistling thorn, unfortunately difficultly precisely to describe this sound) in one ear. What is it can be and where it is better to try to address? Has bothered terribly. Help or assist!

[The first doctor]

Dear Igor. To address it is necessary to an ENT-doctor. The diagnosis can be put only after survey. It can be both a cerumen impaction, and vascular disturbances, and other pathological statuses.
