I have T from April 2016, it started with a very light whispering sound and now it has become a sort of electric buzzing hissing sound. What I can tell you is: everytime I got a spike I panicked more and more, But eventually after less than a month I completely felt fine again, as the spike settled down a bit or I habituated.
So let's hope for the best, my friend!
Read my post on the Ear Muffled. We live on the edge every way hoping it dosent get worse.
