This month is my 4 year anniversary with T. I have both the constant ringing and pulsatile. Been CT'd, MRI'd, drugged, spinal tapped, tested, and prodded, by neurosurgeons, GPs, ENTs, and dentists, and no one knows the cause, but they all agree I just have to live with it. Eat healthy, low salt, no soda, limited coffee, don't smoke, etc., etc. Don't run anymore because the racket afterwards was mind numbing. Some days are better than others, but there hasn't been a good day in 4 years.
