Answer:
I'm not a doctor but this might be something called costochondritis it's a pain of the cartilage that attchs the ribs to the breast bone. It's one of the most common causes of chest pains in kids and teens. Usually this is harmless and goes away on its own after 2 or 3 days. Could be cause because of a injury or repeated coughing (which can happen due to infections). Usually the pain does get worse when you take deep breaths cough move the upper body or press on the affected area. You might be thinking it's due to some heart problems however this is unlikely
Heart attack pain is usually more widespread and felt in other parts of the body. As I said before I'm not a doctor however some possible ways to reduce pain is to apply a warm compress or a heating pad on afectted area. Stay of vaping. If the pain doesn't go away or if it gets a lot worse ask your parents again to go to the doctor. It might also possibly be due to gas build up inside you you stay of things like fast food for a bit. Hope this helps
