Lung or heart problem

I feel like someone has pumped my chest up. If I stuck a pin I would burst.
what is this. i have a small lung cyst would it be the cause, its mainly when I am walking.

I had my 1st af ablation 3 yrs ago and somehow the phrenic nerve was damaged and I ended up with collapsed lung but it came good and I had a 2nd af ablation 12 days ago. is this from ablation or is it a lung problem.
anyone been here. Cheers jran

I have no idea, however my first thought was pleurisy. But I have never had pleurisy and I don’t know what it feels like. But I think given that you had an AF ablation I would want to go see my doctor for a chest x-ray.
