Mine started in my left ear but now I have it in my right. The right is not as loud and I never hear it unless the frequencies are different. The frequencies change a lot.
My son has it. Says it gets worse when he eats salty stuff. It’s so bad he can’t hear anything even with his hearing aids. He’s deaf in one ear and 90 percent deaf in the other.
#7 This is the insect that crawled into your ear and is slowly eating it’s way to the other ear to get out... : )
