Before the thoracotomy, I was in good health, and the wound was very painful within a month. If I bend over, there will be a thumping sound, such as the feeling that the bone is caught by something and then released. Especially uncomfortable. I don't think I can open it. Now more than a month has passed, and I haven't felt uncomfortable yet. I still feel better when I bend over. The wound is on the right side, so if you sleep on the right side, you will still be awakened by pain at night, so I advise comrades who want to do costal cartilage to think about it before doing it.
