Hi, Billy,
I have both pulsatile tinnitus and regular tinnitus, and so do a couple of other people on this forum. I'm so sorry you're suffering from this condition, and I totally sympathize. I've had several tests, too, and they all came back negative. What tests have you had, so far?
I've had both PT and regular T (high-pitched hissing sound) for 3 1/2 years now. Before that, I had very mild tinnitus that wasn't bothersome. How am I coping now? Well, I finally gave up on going from doctor to doctor, trying to find a cure. Instead, I began taking supplements; one that has worked well for me is magnesium, because in the beginning, my PT was so bad that it felt like my whole body was shaking when I tried to sleep. The magnesium is very calming, and it took awhile, but thing have improved. It has gotten considerably better since then, and I can now sleep most nights, and mostly ignore the PT during the day.
Do you have any idea what caused yours to begin? Mine started after I took a blood pressure drug. I'm now off the drug, but the PT remains, although much improved.
You're welcome to private message me, if you'd like, and we can discuss your condition further.
Best wishes, and sympathetic hugs (believe me, I understand!!)
Karen
