pulmonary function---question

[Guest guest]

I have a question for those of you who go through pulmonary function testing

regularly and have breathing issues of one sort or another. Do you ever have

an immediate urge to cough when you lie down? Can this be related to

respiratory muscle weakness or is it something else? I did have pulmonary

function testing years ago and the results were not good, but no one

suggested any follow up and I have not wanted to add one more doctor to the

list. I've has sob for many years in varying degrees and weakness in

respiratory muscles. A recent CT scan did find a small amount of fluid

around the heart, but no one seemed concerned about that and I question

whether such a small amount could induce coughing when lying down.
