As a normally very anxious person who diagnosis herself often, that's going to keep me paranoid.
Mm. Last I heard, it's not uncommon. However, there are other symptoms that come with it being partially or even fully blocked and I have none. The only one I show is the pulsing, which comes and goes and is never constant; in fact weak and non-existent for the most part. That and the fact that it gets quieter and better every month.
Other than that, I do get dizzy spells but that's because of my congestion from a bad cold and they're very far apart when it happens.
I have been checked but no tests have been run as of yet. I'm still waiting on further referral after seeing the audiologist. So I shall see..
