I have this clicking sound in my brain, it s sounds like a hand fan slapping shut if that makes sense, when I get it I feel like I am going to pass out, but don t (pass out) but I am dizzy. It happens all the time, lying down, standing, sitting etc sometimes every minute or two, sometimes I can go for about 30 minutes without it. There is no pain, my ears do not pop, it is not tinnitus. It s inside my brain usually from one side to the other, or just the noise and the dizziness. The noise is unbearable.
