For the past 12.5 years, I’ve worked in a postal sorting facility, in close proximity to some loud-ish machines. I’ve never felt any particular discomfort, indeed, any particular effect from my time spent in the plant.
Last month, I took a ten-day leave, and pretty much stayed home for the duration. Ever since I returned to work two weeks ago, I’ve noticed a constant ringing in my ears. On this tone generator, I’ve identified two frequencies, D7 (2349 HZ) and A#6 (1865 Hz).
It’s primarily in my left ear, although my right ear will occasionally contribute a tone of its own, which I haven’t been able to identify yet.
I’m not certain that this is related to my return to a high-decibel environment, but it would be foolish to not explore the possibility (I’ve had two two-day breaks since my return, and the ringing has not subsided during those breaks). I have not been in the habit of putting in the earplugs they make available to us, but I’m wondering if starting to do so would do any good, or if the “damage has been done.”
Are there any therapies (preferably pharmaceutical, but I’m not THAT picky) that can make this go away?
