I'm sorry to hear how much pain you are in and I know this may not be comforting to you, but I have the exact same issue, since recovering from multiple PEs in mid-June. I was told it would subside after a couple months, but I still have daily aching pain around my right lung that also gets very sharp at times and seems to be aggrevated by shallow breathing from stress/mild exercise, laughing, talking a lot throughout the day, etc. I've been to 2 pulmonolgists, who say it could be nerve damage from the PEs, so I'm now on Neurotin (a nerve med) and just started it a week ago. So far, no changes, but it's a med that you increase the does slowly, so I'm hoping it works. My next step is to visit a pain center to discuss a possible nerve block injection and any tests they can run to confirm that this is nerve pain. I'll keep you posted to see if I can help you also!
Hang in there - I know how hard this is! I'm trying to move on with my life working full time, going to PT for my knee (original surgery that cause this), etc., but it's hard when this chronic pain prevents me from having my normal energy.
I too have had a PE and remember the pain that you describe. It was mostly an achy dull type of pain that came and went. Once in awhile it would be stabbing in nature. The pains did get better over time, it took awhile though...I believe it was a few months before they were totally gone.
I think it is wise that the nurse is checking your PFT's to make sure that your lung function is intact.
I wish I could help more,
Sunny
