A few months ago I found the cause of my pulsatile tinnitus (not my constant tinnitus). I had a dural ateriovenous fistula. I had the surgery May 7th and am now recovering. All seemed to have gone well and the fistula is closed. It was performed endovascularly, and now I have platinum coils and a glue like substance in my head, used to close up those blood vessels.
