I think I developed Tinnitus as a result of going on blood pressure tablets years ago.A couple of years ago I complained to my GP that my tinnitus was getting louder so I was sent for CT scan on my left ear which is where I thought it was coming from,but the results showed no abnormalities so I was discharged.
It seemed to settle down a bit on its own, but recently I have been prescribed Amertrypterline for anxiety and I'm sure this has made my tinnitus louder.
