Patient question: My father is 60 years old and had a stent three years ago, but at the end of May this year, he was checked again in the hospital for a blockage in a blood vessel and then had a heart bypass operation in early June. Can you suggest any treatment for the current situation? What is the reason for the constant pain in the chest after heart bypass? Doctor’s reply: There are several reasons for chest pain after heart bypass: It is very common to have some numbness and discomfort in the wound in the early post-operative period, which can last for a long time, even for several months. The wound pain needs to be identified: if it is skin surface pain, especially when rubbing, it is often the reaction of skin nerve damage, and is not a big problem; but if it is sternal pain (the pain area is deeper), especially when the activity of the sternal area feels a sense of friction, often indicates that the sternum has not grown well, it is recommended to tighten the chest belt, and go to the hospital as soon as possible.
