I had an ablation done in May and ended up with phrenic nerve damage and on oxygen 24/7. Can someone give me some info on this.

My lung dr. said I could be on oxygen forever. My heart dr. says to give it a year. He's pretty confident that I will get off of it. I am frustrated.:confused:

If you've been through this or going through this will you please let me what I have to look forward to???
