Tinnitus is more in the left ear than in the right ear. Once again, it is my left side, and some days there is no tinnitus, completely gone from both ears.
Somedays, I only have the ringing from the left ear, and a few times, the ringing has only been from the right ear.
The ringing sound is never the same, some days it is light and other days it is louder.

When I start to fall asleep, that place where you are between being awake and asleep, the ringing sound goes completely away. It is like whatever part of the brain shuts down during sleep is where the ringing sound is coming from. The ringing always becomes lower after taking a shower.
