Perhaps it was option 2 or 3 originally which is why all the names are the same but over time transitioned into option 1 in a sort of abolition movement.
I'm not a medical expert, but I can safely say from experience that tinnitus can be caused by a huge variety of things with most of them not actually being that serious (cold/flu, earwax buildup, meds, infections, etc.). However, like other symptoms that inhibit daily functions, if it persists longer than a week, you should definitely consult a professional (assuming that option is available to you.)
