Hi Brenda, I read your post about your son and I’d first like to say I hope everything is alright with him. I was born with a congenital heart defect, and in 2017 I had a heart transplant. It’s been 7 years since I had my heart transplant. I had a ct scan of my lungs this past Wednesday, and today my lung doctor called me and told me I have the same thing your son has my left diaphragm is paralyzed. I have the same symptoms as him also. I can’t lay flat or sleep flat. Now I don’t need any help yet for my breathing but just wanted to reach out and see how he’s doing, or if anything helped him. My name is Matt by the way
