What causes back and chest pain in teen? - chest pain causes more condition_symptoms

I am a teenager and then severe pain in the chest, moving to a place in response to physical activity seemed to be. It is to breathe very painful and difficult, but not on a fast or irregular heartbeat. It happened nearly four times an hour, then went out completely and it was more than a day, but now I have severe symptoms of cold and slight fever. Any idea what is it? I thought, such as pneumonia or bronchitis?
