I had catheter ablation done about 5 weeks ago. After surgery I had trouble breathing. It wasn t like trying to catch my breath- I didn t have any air in my lungs to inhale. I had a sniff x-ray taken and Dr. told me diaphragm wasn t working properly and this would last 4-6 weeks. When I just walk my O2 sat goes down to 86 and then O2 is applied per nasal cannula. This is the worst and scariest thing that has happened to me and I ve been through a lot. I just need some reassurance that this is not permanent and I ll breathe normal again. Thank you
