Postoperative recurrence rate of pneumothorax is low, but it can't be so short. The generation cycle of pulmonary bullae is very long. This may be a psychological effect or a normal reaction after the operation. Generally, it will be a little uncomfortable for a while after surgery. I also had a small incision operation on my left pneumothorax. At that time, it was said that the thoracoscope was broken, so my wound was relatively large. Later, after the operation, my back was uncomfortable for a whole year. I made a lot of films, and the results were normal, and then I began to exercise slowly. If you are not at ease, you'd better make a film. This is the most accurate and intuitive way to judge. In addition, I will give you a little trick to judge pneumothorax: mild pneumothorax, compression below 30%. Pain is not the only criterion for recurrence. Of course, sometimes pain is not necessarily recurrence, and recurrence is not necessarily pain. If the compression is small, there are no obvious symptoms. If one side has shoulder pain, back pain and dyspnea, chest pain is dispensable. Lying flat will have a thumping sound (similar to the sound of air bubbles bursting) accompanied by a heartbeat. When you bend over, you will feel the feeling of running water on your back. Lying in bed will be accompanied by the sound of heartbeat, similar to the sound of bubbles bursting. I feel chest tightness when I walk or go upstairs. But it doesn't necessarily hurt I measured it myself, and it's accurate.
