How can a vessel press on the acoustic nerve?
I am not ironic, i do not reject this hypothesis, i just wonder.
I am just asking this question.
Anyone?
My many frequencies, tonal and hissing tinnitus is sometimes accompanied by pulsatile tinnitus, especially right after a make an effort, like lifting weights (the weights of the shopping bags, of course, not gym weight lifting) and that is why i am so curious about an explanation.
If i open my mouth wide, i have somatic tinnitus (for the duration of the opening of the mouth), but if i open my mouth, when the somatic tinnitus starts, if i press on a region behind my ear, that pressing stops that added sound. So, i have another example of stopping tinnitus with pressure. Biting down hard puts pressure one some structure, probably an artery, given that the tinnitus is pulsatile. (when i open my mouth and wait, i see that that added sound is also pulsatile, so i am a case similar with the original poster)
Probably the applied pressure restricts the flow of the blood, which gives that pulsatile sound, and that blood vessel is audible because goes near ot through the ear.
I read that two blood vessels go through the middle ear, a vein and an artery.
