Slight pain in back (lung area) and breathing weirdly?

Hi, I'm 14 and this happened around about 2 days ago. On the morning this happened, I started dancing 30 minutes after waking up. after about 7 minutes of dancing i feel this really painful feeling in my back (around lung area). After a shower most of the pain had gone away but it was definitely still there. i started experiencing breathing difficulty around about that night. I have to take deep breaths alot, because it feels as if theres not enough air going into my lungs.The pain has since gotten better and today if feels as if theres no more pain at all, but its just my breathing. What could this be, I'm really worried and my parents wont take me to the doctor, because I've been there so much already, and they're too busy
