Actually, my acupuncturist/QiGong teacher recommended getting a book by Max Strom called "A Life Worth Breathing." Because I get winded from climbing a flight of stairs, he said the various half-hour plus breathing exercises videos on You Tube, etc. would be way too much for me, which is why I'm glad he'll work with me with my limitations. From my understanding, which could be wrong, QiGong is a subsection under TaiChi and concentrates more on breathing. He told me yoga focuses on breathing, too, which I didn't know. I'm going to see if I can find a good chair yoga video and check out Dr. Andrew Weil's numerous books and articles on breathing. It is so frustrating when doctors and tests can't tell you what's wrong with your health and help you when something clearly is. I at least have a diagnosis, which is a relief! After my last meeting with the thoracic surgeon, I have a clearer understanding of just how my paralyzed left diaphragm is hampering my breathing am not sure breathing exercises will help...but I want to give it a go.
