I am 17 years old and this has never happened (I was on the track team last year, and am doing so again this year). I ran for at most 10 minutes today but had to stop all of the sudden because I had chest pain. The chest pain was not from breathing, because if i didn't inhale or exhale the pain would still be there (just not as bad). Even while walking my heart was racing and chest was hurting. A couple of times I had to stop and squat down. During this time my throat was extremely dry, but I could breathe fine.

Also on top of that, everything began to take on a blueish tint and i felt mildly dizzy (this usually happens when i have low blood sugar, and since the run was right after school, i'm guessing since i hadn't eaten recently that that was to blame.)

Could this be something serious? I will be running again tomorrow so I will see if it happens again.

EDIT: I haven't run in several months if that makes a difference.

Yes! Have you told your parents/guardian about this? It could be very serious or it could be nothing; that is what doctors determine.

you better go see your doc.

Go to the doctor ASAP. you could have a serious medical condition! or it could be nothing serious....just go to the doc.
