I have been batteling shortness of breath for 7 yrs now. I started out being feeling very sick with weakness, sweats,gurguly in throat, feverish and short of breath just walking a few steps or talking a few words. I had extensive testing on my heart, like cardiac mri, nucleur stress test, echo stress. I had cat scan of lungs 3 times. Antiflamatories help and prednisone. It isn't as severe as it was the first 6 months but if I walk a couple of blocks or jump or vacum I get the shortness of breath hours later, lightheaded, feels like my chest is blowing up with fluid. Very uncomfortable and scary. I am so limited...Does anyone else have this issue ?
