In 1980 I noticed that my hearing on the left side had diminished over
a two week period, and had odd crackling sounds in that ear. I visited
my GP, who confirmed some hearing loss on the left side, and referred me to
an ENT at Baylor (in Dallas). The ENT felt that the hearing loss was due to loud noise
exposure (Rock & Roll concerts, firearms, motorcycle racing). And he told me
that it was not possible for the hearing loss to occur that quickly, he felt that the
loss had happened over time and I had just notcied it. I knew that the loss had happened
suddenly, but "everyone knows" that hearing can be damaged by noise. The ENT claimed
that there was nothing that could b done to return the hearing loss. I didn't think
anything could be done, and I began to unconsciously make the little ajustments needed for a hearing loss
on one side.
 Jump to 2002. By this time I had a fairly severe high freguency hearing loss on the left side, but had
always chalked it up to noise exposure. I began to experience odd Aura events, where a arc shaped portion
of my field of view would start flashing with a geometric pattern, for about 30 minutes. After the fifth
such event I went to the ER. They did a CAT scan, blood tests, etc., and ended up thinking the auras were
a precursor to migrain. I didn't really have migrains, but after having everything checked out
was less worried. When the auras stopped, I stopped worrying.
 In September 2005, I had a fainting event, I just keeled over standing on the sidelines after a pickup
basketball game. The ER found no particlular problems, and wanted me to see my Cardiologist. The Cardiologist
referred me to a Neurologist (Dr. Morgenlander at Duke), who after listening to all the above history sent me for
an MRI with contrast. The Neurologist called the second morning after the MRI to report that "You have a small mass."
I don't remember much about that conversation now, other than he recommended that I consider having the
AN surgically removed, and refered me to the Skull Base Surgical team at Duke University Hospital (Dr, Sampson,
Dr.Tucci, and Dr. Fukushima).
 In a way, my Cardiologist was the key to obtaining a correct diagnosis. He recognized that some odd things had
been going on that we could not explain. If he hadn't referred me to the Neurologist, I might still be undiagnosed.

PS. I some ways I'm glad that the AN wasn't diagnosed in the 1980s. I may have been tempted to have the thing treated when techniques were not as refined as they are now
