HI I have had shortness of breath on exertion, particularly when lying flat on my stomach to paddle while surfing. Sitting up relieves the issue. Had a chest xray which states right hemidiaphragm elevation. cardiomediastinal silhouette within normal limits of size , mild calcified plaque in the aorta, left lung well expanded and clear consolidation , Right costophrenic sulcus blunting and pulmonary vasculature within normal limits no edema and bony thorax intact. I believe the elevation of the right hemidiaphragm is something to be of concern.
