Pain and redness when talking for any length of time

[Derekhhh]

Hello,

I have had an undiagnosed problem for about 6 years now.  I've seen about 20 doctors, even in the best hospitals in my city (in Asia), and the problem remains, which brought me here.

Symptoms:
- When I talk for a period of time (depends on how loud I speak, and also depends on dryness of the air I think), I feel a pain or dryness (or swelling?) in my nasopharynx area.  The whites of my eyes, and my eyelids become red as if I'm very tired, and my eyelids swell.  If I continue talking, I begin yawning and the pain in the nose increases, and it feels like my nostrils are small.  If I continue and continue I get headaches and feel like I need to sleep (but this happens rarely).
- When I wake up in the morning, I feel better.  But in the past year, I always wake up with some redness in my eyelids.  My eyelids never look fully healthy or normal.. always there is some redness.

History (forgive me if this seems long):
- I grew up in Colorado - extremely high elevation.  
- I had surgery at 8 because of sinus infections (probably because I was sleeping with the fan blowing directly into my face) and I had nasal polyps at that time.  After the surgery there was no problem.
- at 24, I moved to Asia (first Thailand, then Japan, China, Taiwan, back to Japan).  The problem started where I felt like my nostrils were too small.  Doctor couldnt help.
- the problem started where I'd feel the symptoms above at 25 or 26.  Here's what the 20 doctors said.
                    - "it's because of some allergy"
( I took allergy medicine which relieved symptoms maybe by 30%.  But it might have been coincidental.  I took an allergy blood test twice which showed no allergy in body, overall.
                    - "the air is too dry"  
Doesn't make sense as I had the problem in Thailand too and also when I returned to America, in California.  However, when I wear a mask when I speak, the problem greatly decreases.
                   -  "Your nostrils are naturally small"
But that doctor seemed like he didn't know what the heck he was talking about and no other doctor said that.
                   -  "I don't know"
Many said this
                  -   "You have rhinitis"
                  -  "It's because of your allergy to house dust"
This is the most recent diagnosis.  But I was told many many people have this, but show no such symptoms.

Here's what I already did:
- catscan and MRI  - showed nothing wrong
- the video stick thing they put up in your nose and see your sinuses and throat
                 It showed nothing but the throat seemed swollen and I was told I had larangitus.. but that also went
                      away.
- allergy blood test- showed only house dust allergy, but I've heard the tests don't show all allergies


To put it short, I've looked everywhere and can't find any sickness that takes place when someone talks for a period of time.  Has anyone heard of this?  It is a serious matter to me as it great effects the quality of my life.  I'd appreciate the help!
