When I get sick, I seem to breathe better. I was told by my allergist I have moderate asthma and lung restriction disease. I also had a high allergic reaction to dust. But the pulmonologist saw my pulmonary function tests and CT scan and said my lungs were clear. He said if anything I had mild asthm and my scoliosis was causing breathing problems. I find it strange that I breathe better when I’m sick. Also being outside helps. Could this be sick building disease or multiple chemical sensitivity, adrenal fatigue or my hyperthyroidism causing this? If anyone has experience with breathing issues related to something else besides asthma, please comment. Thanks!
