I have had Pulsating T for a year now. The last few months have gotten much better, can go hours without it bothering me. I also was taking Klonopin .05- 3 times a day. I started to taper down slowly and then noticed a hissing noise of my left side develop. All the progress I have made has taken a hit, my anxiety and depression has come back, though granted not as bad as it was before. I also take an AD which I need, I have had depression for 25 years. I know it is wrong, but I am so concerned with the new noise.
