I think I've just realised this is the latest fun symptom handed to me by perimenopause. It's like a constant morse code type beeping in one ear - it's quite low frequency, and I can really only hear it at night/when it's very quiet, so thankfully not too disruptive at present.
Thing is, once I noticed it a few days ago, I remembered having it before - I first noticed it when I was pregnant, and then it went away again afterwards. So I did some Googling and it appears tinnitus can be linked with hormone changes.
Just wondering if anyone else has experienced any kind of tinnitus in peri/menopause?
