If the lung has been treated surgically there will be post-operative healing and there will be some sequelae, which really depends on how much the scarring after healing affects lung function. If there is still some painful pulling when you have just had surgery, or if you cannot breathe deeply, you need to do post-operative rehabilitation because that is where the sequelae arise. If the rehabilitation is done well, the exhalation can be opened completely at the later stage, and there will be no more pulling pain, and the lung function can be restored to normal, and the sequelae can disappear completely, which depends on whether the rehabilitation is in place after the surgery. If no rehabilitation is done at all, it depends on luck. Some people may pay attention to activities or be in a cheerful mood and recover well, while some who cannot do so will have pulling pains or lung function will not return to normal, and these are considered sequelae.
