Hi everyone, For many years I have a distinct pulsatile tinnitus. When my head / neck are in certain positions, such as sitting with my neck slightly tilted forward, I hear a medium high pitched whining sound which goes from high to low like a car passing by Hummmm hummmmm hummmm etc. Actually, it sounds 90% the same as the one, only not as loud and slightly lower pitched: https://www.tinnitustalk.com/threads/the-sound-i-hear.16947/ When I look upwards or sideways, it dissappears. The Doc told me it is just some arteries which are vibrating because of they way they are 'placed' in my head. Maybe some of them are bended or something like that. No need to panic until it gets worse. Anyway, since this morning I have noticed something has changed. In the position as described above, I can still replicate the exact same sound, but if I tilt my head slightly, the sounds become shorter. So instead of 2 second bursts of hummmmm, i hear now 0.5 seconds hum hum hum. When i tilt my head slightly back again, the sounds become longer and back to the old pattern. It sounds like either my arteries are vibrating less, so it has improved, or blood flow gets restricted all together and thus it got worse. Can't figure it out. I worked yesterday as a cameraman, which means heavy lifting and looking at a monitor which is on the left of my vision so i tilt my head a lot, maybe that could have something to do with it? Is it possible that some arteries could be completely 'shut of' in some positions and therefore i don't hear them vibrating anymore like I used to? Would that give me other symptoms? Or could it be that something actually got better? What do you guys think?
