I woke up this morning and the ringing was minimal in my left ear and almost absent in my right. As I took a shower I blocked my ears and I realized what silence sounded like.
Now the ringing seems to be gradually returning. More in the left than right.
Definitely two distinct sounds.
Interesting. I will cure myself.
Addendum
I just at breakfast. The ringing is back but not too bad. The sound is more on the left. It seems like it is coming from my inner ear vs hearing one sound somewhere is my head.
The sound also undulates. Not a constant noise. I can hear a higher frequency noise and a very slightly staticy kind of noise. I can also feel a low level reverberation more on the right. Almost like hearing a car or something idling.
Stay tuned.
