I've also wondered about that. I didn't feel like I had tinnitus (I have a very mild one) until after I moved my apartment to a noisier street and wore earplugs for about 2 weeks.
Now I have a very faint one that "toggles" once or twice a week and ALWAYS when I wear earplugs.
Are you suggesting that I get checked for an ear infection or saying that I should stop using ear plugs? I have pretty much done the latter, only wearing them for the occasional nap once every other week.
I'm suggesting if you ever do get an ear infection to seek medical attention asap.
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]
Same here! I had very faint tinnitus (from headphones in the office all day), but after we moved offices (open office space) and I started wearing earplugs UNDER my hearing protection earmuffs, my tinnitus started going wild.
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.
Now I have a very faint one that "toggles" once or twice a week and ALWAYS when I wear earplugs.
