FWIW, I have ringing in both ears. I can't count how many years, 20 steady years maybe.

Sometimes it may change it's tone. A higher pitch or a steady ringing sound. Other times it seems like a buzzing or swooshing in my ear, like I can hear my blood going in my head.

A few times it went real high pitched and then I lost total hearing in that ear for a few seconds. It comes right back, TG.

I used to be able to hear a noise on the outside street, before my dog would, and he had great hearing. Now I blast the TV and Stereo. My DH gets in the car after I had it, and it blasts him when he pushes the button on.

I hear background sounds first, then voices. So at a party or a crowded place, if people talk to me I hear the music first and have a hard time hearing their voices. I am getting good at lip reading.

My ENT and Neuro said it is probably a lesion in that area. I put the radio on or TV, even a fan to drown it out, so I can ignore it.

I thought it was from having Measles as a kid. I had so many ear infections with that illness, and after that for years. Who knows? It's hard to determine.
