I have pulsatile tinnitus. I went to the ENT, also had a hearing test and MRI all were normal. I have had this in my left ear about a year now, I think. Especially at night going to bed. If there is noise I do not notice it. Yes does drive me crazy sometimes but at night. I guess it is here to stay. Mine is a swishing sound.Good luck to all and see an ENT it does not hurt!!
