Hi, Kim,
Yes, I've been to several doctors, and had a number of tests for my pulsatile tinnitus. What started it all was blood pressure medicine, so I am pretty sure I don't have any other problems. The blood pressure medicine first caused a very loud ringing/hissing tone, and about a couple weeks later caused the pulsating to begin. It hasn't stopped, but it has gotten much, much better since I got off all those drugs!
I take a baby aspirin every now and then, and it hasn't caused any problems with the tinnitus. But every day, I take one Carditone tablet, and that has really been helping. My blood pressure is great now! I think that was my problem all along.
I'm glad yours has gone away now, too. Let's hope for better days ahead!
