I was diagnosed 4 years ago with low oxygen levels with exertion after a mild case of COVID and a bad reaction to the COVID shots. My pulmonary lung function tests showed mild restrictive lung disease. Cardiac testing showed I had heart failure and pulmonary hypertension.

I started seeing a physical therapist regularly, and she taught me how to breathe correctly, improve my posture, and engage in home strength training.

I am now off oxygen as my fitness level has improved. My oxygen level will drop into the low 80s during exercise without correct breathing and will increase to 95 with correct breathing and posture.

I started out needing oxygen 24/7, but I am grateful that I have improved. With mild activities of daily living and moderate exercise, I don't need oxygen during the day or night.

Medicare has paid for all my visits during this time. I have multiple diagnoses -hypoxia, osteopenia, arthritis, neck and back pain, which helped with insurance coverage.

Physical therapy may help you.
