Hi John -- one of the people in the FB group for people with paralyzed diaphragms had the same experience. As a result of his being a superstar (my word) and consistent strong swimmer, he was able to restore his lung function completely and recover from the effects of his paralyzed diaphragm through swimming. It's pretty amazing how the body can heal itself. I'm so happy for you! Every time I read one of his posts on FB that mentioned swinging, I thought about you. You were the first person who reached out to me when I started my journey looking for information about my paralyzed diaphragm, and that really meant a lot. Thank you!
