Hi Chuck,
I have had 'squirrely' chest xrays and CT chest scans ever since I had radiation. If the upper part of your lungs were radiated, that may be the cause. They can scope your lungs the same way they do your throat, but the have to knock you out to do it. If you think you'll stress out oo badly or if doc not sure, I'd ask about it.

Take care,
Eileen
