I m 14 and I have had differing chest pains for a few years. Last year they sort of disappeared but in the past week, they ve come back. The pains differ; from sharp stabbing pains, to long aches and a lot in between, but they all seem to centre around the chest and arm area. Lately I have had a constricting pain across the middle of my chest, which is really quite painful. It hurts a bit more when I breathe in. I also had this pain in my shoulder a few days ago. I read on the internet about something called chostrochondritis, which is a common cause of chest pain in teenagers. Is this that? I m scared because I don t know if it is cardiac. Also, could it just be growing pains, as my parents suggest ? Please help, I m worried. Thanks.
