When was the last time your lungs were scanned? They did mine three times within a year post Tx. The first 2 had "areas that could not be excluded" and the last thankfully was all clear. With all the crap going around this flu season it may just be a bug or a pulled muscle from exercise. Sometimes I think I do more harm to my body exercising than good. But you're correct about contacting your doctors. It's never good to put anything off with our history.
