question: Hi. I have been ill with mild chest congestion, intermittent cough that does not produce mucus, and fatigue, since mid October and we are now into January. I have had an echo cardiogram and stress test and pulmonary function test. I can take in and exhale a full breath, it just hurts to do so. I passed the stress test well. I can run, but I don t have the energy to do so and breathing becomes more difficult. I was given a zpak and inhaler that did nothing. I have no idea where to go from here and my doctor seems to be stumped. She offered another chest x-ray, but with no change in my symptoms I d expect the x-ray to show the same results (no signs of pneumonia). Thanks.
