Hi Duncan who posted in 2018. I think I have Pulsatile Tinnitus Yesterday I had an MRI /CT with normal result.I began Bisoprolol Furamate in September 2019 and now I see a connection. Earlier on today I asked a pharmacist to look at my meds and see if any might be causing Pulsate . Hopefully, this is the cause of mine and stopping it with Doctor guidance will stop this more than frustrating swishing sound.
