That's the thing, it is usually hard to tell when and what caused the nerve damage because one sided paralysis of the diaphragm doesn't usually cause too many problems and is found many times incidentally on a x ray some time after the event.
Any procedure that involves manipulation near the phrenic nerve, as well as infections runs the risk of affecting that nerve. At least that is what my doc has told me.
I hope this helps,
Sunny
MY HUSBAND HAD OPEN HEART SURGERY IN 2013 AND A MONTH AGO WAS DIAGNOSED WITH FROZEN DIAPHRAGM NOW WE ARE WONDERING IF THIS WAS CAUSED BY THE SURGERY?
