Hi everyone, Elizabeth here, I have been so interested in the subject of shortness of breath. I have that to a mild extent but the thing I have been experiencing for many years is a sort of pressure and/or bubbling effect in the middle of my cheast. It is not a pain and it does not radiate in any way. My doctor had me take a stress test to see if my heart was involved and, thank God, it was not. I had a lung test and the technition could not believe my capacity at my age. My doctor has no idea what the problem is but perhaps it is PD oriented. As I look back I believe that it started with the slight tremor I experienced for many years. Thought it was just a phase of growing elderly. Perhaps, perhaps, wouldn't it be nice not to have to guess but to have a test to tell you. Keep smiling kids,it really does help Elizabeth
