So my tinnitus started a few weeks ago with a ringing in my right ear. After about a week it was a hum in my left that I noticed. Now I have that ultra high pitch ringing in mainly right (but feels like it's in my head). This has been with me (or noticed) since Friday, so nearly a week. I have no hearing loss and am hoping I'm lucky and it all goes. But if I have a base, I hope this ultra high pitch is not it!!
