I have a problem of being so short of breath. I have to stop and take a deep breath when talking to some one. Told my present doctor about it today + got a blank look as I had a work up for that problem a few years ago with no answer + it has gotten progressively worse.Also when I bend over it seems to shut my air off. At times I start yawning and can`t seem to stop which have been told it is a lack of oxygen. The Dr. said he would think about it + maybe have me see another pulmonary specialist As I don`t see him for another month I don`t feel that was an acceptable answer.Anyone have any input on this problem or share this type of problem?
