I wanted to update on this. Since getting this shot, my tinnitus has been much worse. I seriously regret getting it. It spread to my other ear just as bad, maybe even worse than my right, and it's louder in both.
I still don't know if I got the real thing or not, but all the worsening started right after I got the shot. In fact I felt I was slowly getting better before it. Not anymore. I don't talk about it much, but I was hurting hard before I got it. Now I'm hurting even worse. Don't try this drug. I'm hoping this is temporary and will report of if it is, but its been a month of only getting worse since.
