Hi, Madays,
Your PT sounds very similar to mine. Back in 2010, I took a blood pressure drug, and my pulsatile tinnitus in my right ear started within about a month of taking it. I no longer take blood pressure meds, but my pulsatile tinnitus remains. Also, before it started, I had mild regular tinnitus in my right ear. After taking the drug, my mild tinnitus became much more severe.
I've had an MRI, CT scan, and Doppler of carotid arteries, all of which were negative. I've been to several doctors and specialists, and they could not find any cause for my PT.
I have heard of other people whose tinnitus and/or pulsatile tinnitus started after taking a drug, and I believe that some of us may be more vulnerable to this condition. In my case, my right ear might have already been weakened by the regular tinnitus in that ear.
Like you, I also experienced dizziness/vertigo, feelings of fullness and pressure, and a great deal of anxiety. I do want you to know that the dizziness/vertigo has disappeared now, along with the feelings of fullness and pressure, although my increased tinnitus and pulsatile tinnitus remain. I have become more used to it, and have been able to get back to living my life normally again.
I wish you the best, and hope that some of your symptoms will dissipate as time goes on.
Best wishes,
Karen
