January this year I awoke one night with a very loud and high pitched tone in my left ear much like an old CRT TV. Over the last five months it started moving between ears, sometimes both (right now it's only in my right ear) and the solid tone has gradually become a tweaking jingling noise, like a tiny bird chirping in my ear or like a tiny chain being jingled. It follows no pattern and the volume climbs and falls randomly. Some days I wake up and it's gone until the evening. GPs have been less than helpful sadly, took a hearing test which came back normal for my age and I saw an ENT who had nothing to offer other than recommend an MRI. I've not found much if anyone who described tinnitus like this, any thoughts would be appreciated!
