I'm 16 years old (female and in very good shape and health) and I've been having chest pains since I was 13. At first I didn't think much of it- I had a little "attack" once every few weeks. it was a sharp pain and I couldn't focus in school because of it. The pains lasted around 5-10 mintues. As the years went on the attacks became fore frequent. When I was 15 I started a new vigorous sport and the chest pain just was so bad it lasted all day long and I couldn't even do my sport because It felt like I was being compressed. I went to the doctors and they said I had costochondritis so They prescribed anti-inflamitory pills. Those didn't help- obviously. Now my pain is very frequent and is all day log and lasts days and there's shorter periods of time In between where I don't have the pains. It's so achy and it really hurts, I've been to the doctor twice and they both said costochondritis. But I want to go again and I also don't because I don't want them to keep saying the same thing- but it's starting to really effect me and it really hurts. please help!
