Many possibilities: The most common cause of ringing (tinnitus) is hearing loss. At your age, it is unlikely that the cause of your tinnitus is hearing loss, but it needs to be ruled out.

The cause of the hearing loss can be speculated at based on your history and the findings from the hearing test. There is no imaging study that can quantify hearing loss. ...Read more

The cycle switches sides ~every 15 minutes. Mild to moderate nasal congestion adds a little more blockage & makes one aware of the normal process. So this is more likely a typical allergy than permanent hearing loss. ...Read more

Chance of that happening? NEAR ZERO. ...Read more
