Last week I went to my doctor the second time this year because I was sure to be allergic to something. When I went the first time (in spring) my doctor wanted to wait until the "pollen season" is over. Since I still have the same symptoms now that it's winter I visited her the second time.
She tested my IgE, did a Prick-Test, an x-ray of my lung and auscultated it. I'm obviously not allergic.

Don't get me wrong, I am happy to be healthy.
But - I still wake up every morning with a running nose, itchy wet eyes and hurting lungs (my lung is ok on x-ray). It feels as if I had spend the night in an smoke-filled pub (which I haven't ) Sometimes I wake up in the night coughing and it won't stop over extended periods of time. The problem is especially annoying while doing sports, I can't breathe through my ever-running nose when running and sometimes have a hard time breathing when biking or swimming, because my lung somehow feels blocked.

My doctor had no explanation to this and I felt hypochondriac in the end (which I don't think I am, I visited the doctor the described two times in the last 5 or more years).

I am at a loss. While I AM happy to not be allergic, I would like to feel that way, too.
