Ear Help & Guidance Needed

I'm not a big fan of posting my problems online, but I'm confused and
concerned about this particular situation, and I'm hoping that some of
the readers here may be able to help.

About 6 weeks ago, I began noticing a strong ringing in my ears,
specifically it was worse in my right ear. Occasionally I feel like
someone is putting a finger in my ear for a few seconds, putting
pressure on the ear itself, but it doesn't last. Also, about twice a
day I have the sensation of a strong ring for a few seconds that seems
to take over a particular ear, and then dissipates rapidly.

The ringing became obvious to me rather abruptly, and has been problem
since. The reason the situation has become so difficult for me to
figure out is because there are many possible contributing factors,
some obvious and some not, all of which need to be considered:

1 - I've had ringing in my ears in the past, and I noticed this abrupt
change within 48 hours or so after a Scuba Dive in Hawaii to approx.
50 feet. During the dive I felt discomfort in my right ear (the ear
that's ringing the most) about half way down, and stopped my decent
long enough to equalize better (about 2 minutes), then continued with
the dive. On my way to the airport about two days my right ear was
hurting, and I thought I might be coming down with an infection or
something. This concerned me because I was about to get on a plane.

2 – A few days after I got home from my Hawaii vacation, I got sick
with a severe cold. This cold lasted about 10 days. I'd say my
recovery was about 20 days ago.

3 – And here's the curveball! I'm a professional recording
artist/record producer. I'm exposed to loud sounds on almost a daily
basis, and although I use hearing protection much of the time, I've
been doing this on and off for almost 10 years.

Today I went to my primary care doctor, and I couldn't have had a
worse experience. My typical physician wasn't available, so I sat with
another gentleman to discuss the problem for maybe a total of 4
minutes. When I told him I was a musician, he automatically defaulted
to scenario 3 as the cause of my trouble, then referred me to take a
hearing test in 3 weeks! He did not give me a referral to a ENT, which
ticked me off to say the least after I left the office and had a
minute to think about it. I'm self-employed, and problems with my ears
= problems making a living. I can't think of a better candidate to see
an ENT.

So…

What should I do about my situation? Could it be time-sensitive as in
I should find an ENT immediately? Could scenario 1 or 2 be a cause or
is that just wishful thinking? Other than hearing damage from loud
noises, what other problems might I be having that could be
contributing to this situation? Are there any other resources I might
check online (other google groups, etc.)?

Thank you all so much for taking a moment to read this, I really
appreciate and advice and/or guidance you guys can provide.

Thanks again…
