Thanks for your response alice md

Just from the conversation with the person doing the lung test I got the impression it was to check for asthma. I explained to my doctor that, despite the test results, I was so weak I could barely walk out of there but he will still not do more. If I ever get to see a specialist I will try and mention further testing.

I had such a bad night last night that I almost went to the hospital but that really does make my anxiety worse so I took my chances at home. One day I will take another chance on the emergency doctors but comments made to me the last time are still too fresh in my mind that I'm just not ready. If I get bad enough I suppose I will have no choice

Thanks again for your response,
