You are a 15 year old male with chest pain when I twist move sneeze take a deep breath it is a crushing pain in my sternum what is it?

Please go to a doctor. Tell your parents now. If I'm not mistaken, I believe it is congestion in the lungs usually a sign of the flu or Allergies. I had this as well, I took some decongestant and it went away in a couple of days. If this remedy does not help definitely go see a doctor right away.
