The pain after thoracoscopic surgery usually takes 2-3 days because thoracoscopic surgery is minimally invasive, and the incision of the surgery is relatively small and traumatic. After the surgery, the hospital needs to inject anesthetic for nerve closure in the vicinity of the incision, and the pain will be significantly reduced after the surgery. After the pain is reduced, it is easy for the patient to cough and blow up the balloon, which is beneficial to the lung reopening and the recovery of the disease. Generally speaking, after thoracoscopic surgery, the pain should be 2-3 days. We should communicate with the patients that they should cough and blow balloons more often, which is beneficial to the recovery of the disease and early discharge from the hospital.
