Chest pain after surgery for early stage lung cancer may or may not be normal. It depends on the situation. Normal chest pain may be caused by the failure of anesthesia, pleural fluid receding and pleura rubbing against each other. During surgery, anesthesia is usually used to paralyze the patient so that the patient feels no pain. After the surgery, the patient will feel pain when the anesthetic fails and the patient regains pain sensation. It is also possible that the patient is emotionally unstable after the surgery, resulting in chest muscle spasms triggering pain. This is a normal phenomenon, no need to worry too much. If the wound recovery process will produce a certain degree of inflammation at this time the wound is recovering, the emergence of pain induction timely medical treatment, in order to prevent inflammation and infection is not conducive to postoperative recovery.
