The first attack of pneumothorax is usually treated conservatively, if the lung compression is less than 30%, no special treatment is needed, rest and observation; if it is greater than 30%, puncture and suction is feasible, if the puncture and suction are not effective, closed chest drainage is needed. If the pneumothorax is more than the second attack, it is recommended that surgery is the first choice, thoracoscopic surgery, which is not very traumatic and has good results, but there is also the possibility of recurrence, but the possibility is relatively small. If you do not want to operate, then you also have to perform closed chest drainage, but the possibility of recurrence is higher. After the pneumothorax is healed, you need to insist on exercising, which will reduce the possibility of recurrence. Exercise needs to gradually increase the amount of activity, not sudden strenuous activity. You can walk slowly first, then walk fast, then jog, the purpose of exercise is to increase the activity tolerance, so the time should be longer, long-distance running is a good choice.
