It is really helpful when you have a specific event where your phrenic nerve or diaphragm was injured that resulted in a weakened or paralyzed left or right diaphragm or both. I'm glad your treatment is helping you and hope it will restore full function of your diaphragm. Paralyzed diaphragms can result from accidents, operations, viruses, vaccinations, etc...and most of us who have had the condition with no symptoms for decades will never know what caused ours, sigh. Most doctors recommend waiting up to two years after the recent onset of a Paralyzed Diaphragm before having any type of surgical procedure to see if the phrenic nerve will heal itself. It sounds as though your is...which is outstanding news!!!
