I have had a problem with heart burn lately. And trouble breathing while I sleep. Also when I run or do any physical activity where my breathing gets heavy. My chest and Esophagus burn and I get this wierd short ness of breath where it feels like my heart is missing a beet, once ever like couple mins. when im trying to recover. I'ts to the point that I can't push threw it working out and I have to stop after about 10 min,. I have had chest E-Rays done and doppler and they both came back normal so I'm guessing it's not a heart issue. Plus it takes alot longer to recover. where two years ago it wasnt such a problem to excersize. Is this a normal sign of being out of shape that I can get threw or does this sound like a breathing problem or allergies which I have never had before? or something I haven't thought of It's very frustrating after being in great shape and being able to run 4 miles just 2 years ago.
Please post I'f you have any information Thanks.
