When I stand, especially after sitting a while, I get a dramatic increase in sound intensity after about 10 seconds and then it decrescendos quickly again. When I bend over the sound intensifies also. If I am lying down relaxing the sound can get so quiet at times I barely notice it.I don't really know how to get anyone to take pulsatile tinnitus seriously so have kind of given up. Conserving my energy.
It's interesting because in the morning my pulsatile tinnitus is almost non existent. As soon as I stand up it's back, along with ear fullness. I think it's a dilating vein putting pressure on something it shouldn't be, who knows.
Perhaps when you are moving about your heart works harder to pump blood to your brain. As the blood flows faster and harder it causes your pulsatile tinnitus to become more noticeable. The question is what is causing it? It could be an arterial cause, such as an arterial venous fistula. It could be a tumor. It could be any number of things. That is what makes it so scary, the uncertainty. If you press on your neck does it alter the pulsatile tinnitus at all?
