@anniepie I had tinnitus off and on from back in the early 1990's. It was never too loud and would go away often for long periods of time. My tinnitus became pretty severe this past summer and it is either from the azithromycin or tobramycin - it began when I was finishing up the Tobi and starting on the azithromycin, so I'm not sure which one got it going but now it's loud and almost constant. I have learned to ignore it a good deal of the time, but sometimes it's just not possible. Just another new "normal." I have seen a commercial on TV about a group that can help people with this and read an article about it. If you Google, you can probably find some information but my ENT told me it is what it is.
