I have pulsatile tinnitus for the last 12 years, however it's also accompanied with a CONSTANT sensation of pulse, as if I can feel my arteries dancing, all around my scalp. To this day, the doctors have been unable to find the root cause for either. I eventually learned to live with both and came to terms with the idea that I will never find out why this happens. With that being said, I want to pursue a diagnosis for curiosity's sake as soon as my financial situation allows it.
