Shortness of Breath

[Guest guest]

I was diagnosed with polymyalgia rheumatica in 1997. At the onset I noticed I

had shortness of breath upon lifting heavy objects and sweeping floor. It comes

and goes and I even have good times when I can walk a tred mill. I have not

tested positive for RA but did have lung studies and have been diagnosed with

pulmonay fibrosis. I am now experiencing something strange which can't get a

satisfactory answer for. At rest I suddenly have a spasm of my diaphragm with

causes me to take a sudden rapid deep breath. I have no control over this and

it is getting painful. Any ideas of what is happening. Thanks
