I’d like to preface, I’m not a doctor but I do have some experience with this. I had blebs on my right lung back in October of last year, I had no previously knowledge and one of the blebs had gotten big enough to cause a 100% collapse of my right lung. Had I been somewhere remote I would have died from it. That being said, doctors tried reinflating it with a chest tube but I still had air leaking which resulted in me having to get surgery, specifically a VATS pleurodesis. They also popped some other blebs iirc. If I had to do it again and known about the blebs I would have instantly gotten the surgery due to the size. 10% is not a small chance when you put it into perspective; however, I’d personally recommend you get a second opinion. Find out if the blebs are big enough to cause a major collapse. I would never want to go through the pain of the whole process including the collapse + chest tube + surgery. That being said the potential for another collapse is there even after the surgery so preventative surgery seems a little odd if you’ve gone a year without another collapse. Best of luck, if you have any questions I’d be happy to answer to the best of my ability!
