In the interest of accuracy, I also just realized I used Neosporin yesterday for the first time in years, which I was supposed to avoid because neomycin is known to cause/worsen tinnitus. So the reason my tinnitus just got worse is very likely was the topical neomycin (or perhaps a combination of the neomycin with the procedure). Either way, I'm seriously bummed out. It had gotten so much better. Hopefully it gets better again.
