I’ve just started having it (right ear only) in the last month. It’s not very loud, and I only notice it when it’s relatively quiet or I’m thinking about it. Most of the time I’m not aware of it.
I have no apparent hearing loss, but I’m seeing an ENT in a few weeks for the vertigo I’ve been having on and off for the last three months, and they’ll check my hearing, too.
Naturally, I’m wondering if the tinnitus is related to the vertigo, and hoping they’re not a sign of something more serious. (Fortunately, so far I don’t have any other symptoms of Ménière’s disease.)
