Hello@pc2018 and welcome to connect. Have you tried breathing exercises for this condition? I was in a Paced Breathing Research Study for 3 months as a result of lung cancer VATS surgery to remove an upper left lobe and a wedge from my lower left lobe. I understand well, the challenges of breathing.
It may be worth a try...Dr Amit Sood has some great techniques, but you must practice several times a day. for a minimum of 15 minutes each session. I was desperate to breathe again and the program not only helped be breath...I am now a runner as well as a 10 year lung cancer survivor.
