I hope it works!
I have low oxygen, short of breath, asthma, wheezing, coughing, etc. I have been on oxygen full time, but now mostly as needed. I was given an article about Parkinson, PT, and breathing. I gave it to my pulmonary doctor who set up a PT once a week. As I said before, amazing progress. The key factor was that my doctor read the article! Good luck. Blessings, JudyTx 🌹
