Yeah I also get like 'time to time' tinnitus too, as an added layer on the perma-tinnitus. It comes and goes in a few seconds or a minute which is pretty weird.

So I'm living through three types now...

I wonder how much could be caused by things like stress or exterior aggrivation like you suggested, PTSD etc. These things can do a surprising amount of seemingly unrelated stuff (skin quality too, apparently FYI).

So far, i'm another day or so in and I still basically have no extra ringing, can't explain it at all but not complaining =D
