After ignoring the warning signs and also having an ear infection which I never bothered getting medical help for it got much worse.
It's settled down to a manageable level for me now but heed the warnings, you may save yourself a lot of misery in the long run.
I had a random infection a few years ago and just waited for it to pass. Which it did, eventually, but my tinnitus became much worse afterwards. I'm guessing, because the infection did further damage which could maybe have been avoided?
I can't say whether you should stop wearing earplugs because you may sometimes be in a situation where they protect your hearing. But, for blocking out background noise in an office, they're probably not a good idea? [based purely on my own experience]
I think it's because when you double-stuff like I did, the only thing you can hear at that point is the ringing in your ears (and high heels on concrete floors). My brain seemed to lock in on the ringing at that point.
When I wear earplugs, the tinnitus is more prominent, so after I take them out, my brain is kind of "latched" on to it for a while.
Now I have a very faint one that "toggles" once or twice a week and ALWAYS when I wear earplugs.
