You know I wish I could help but when it comes to breathing tests, I just don't understand them. When I had mine they would push me and push me until I just couldn't do it anymore and they would say, "Well we can't use this test result" What the heck does that mean?
My pulmonologist then said, well I think your MG is your main problem with breathing. Go figure, so well and I know this is wrong, I just stopped going to my Pulmonologist.
I so wish I could help you. Maybe Annie can
