Hey Brian,
I would ask him if there is something I should be doing? What about excersize?
What meds he thinks I should be taking and why? Have him explain side effects and how those meds would mix with other meds you may already take.
Tell him about the lung/breathing problems you've been having if any. Tell him of all your major concerns & symptons and ask quesions.
It would be a good idea to have them all written down ahead of time. If you've had tests, maybe you could have the results of those with you. At the very least, the date you had them and the results told to you by your doctor.
I don't know if this has helped, but good luck...I'll be keeping good thoughts.
Hugs,
Pat
