Hi, I am 15 years old. I am a female, and I am ppretty healthy. I m really never sick. About a couple months ago, maybe, my chest just started to hurt badly. The pain is in the center of my chest, right between my breasts. The pain radiates to my back, and it kind of numbs my shoulders. It s kind of hard to explain. The pain feels like someone is sitting on top of my chest. It s like I m being squeezed really hard, and it hurts really badly. I have to move around to relieve it, but it only lasts a couple seconds then it s back. It comes and go s at random times, and lasts about 20 minutes. I can breathe, but there s a lot of pressure. Should I see a doctor, or is it normal? Thanks for the help, I appreciate it a lot.
