Every night does my ear make a strange sound?

Every night, always at night, my ear is making a strange sound and it bothers a lot. It sounds like the sound of the sea, it seems that there is a sea inside my ear, I spent an entire night with dry cotton and another night with cotton wool and the sound did not stop what I have to do?
