I also took Clonazepam after I injured my back, a very low dose. I micro-tapered so as not to have side effects, such as tinnitus. My tinnitus began after stopping but it was so mild I barely noticed it. I didn't know it could increase. I just thought it would fade. It never changed, most of the time I did not hear it at all. There was no habituation, no anxiety, it was just there when I listened for it. I had read that it would eventually go away and it might have, had it not been for the stress of the pandemic and an acoustic trauma. It was starting to get better, more like static and then I had the vaccines. It has been mostly a high pitched ringing since then along with dizziness. It has been a challenge to say the least.
