I wouldn't worry at all about having an acoustic neuroma at all to be honest, you'd be presenting a whole bunch of other symptoms like progressive hearing loss, balance issues, vertigo, hearing distortion, etc. The 1 in 100 diagnosis is also
way off if I recall correctly, it's much more rare than that.
Actually just had a quick look on Wikipedia:

So yeah, stress less buddy! I would try to get into that AM-101 if you fit most of the criteria, don't be too quick to exclude yourself because you might think you have something like this causing your tinnitus, take every opportunity to get the best help you can get.
