Thanks guys for the come-back and Bill (Greybeard),I'm sorry about what is going on with you.I had a bad breathing problem too and was diagnosed with mild emphazema about fifteen years ago so I gave up the ciggarettes.About four years ago ,I again had a breathing problem and they found a half inch hole in my heart ,in the septum between the left and right ventrical.I wasn't getting enough oyegenated blood to my lungs.They plugged it up at the Cleveland clinic.I still have a problem breating but I went from 160 lbs to almost 200 in the side of a month and can't get rid of it.I am only 5'7" so it is a chore to bend over and tie my laces.Don't wait till it is too late,getter done! Hope all your tests come back negitive and that it is nothing serious.Good luck!
