I'm no doctor, but that sounds an awful lot like you either breathe with your mouth open or run when the air is too dry/cold.

Your respiratory system could be really dried out. Take a few days off, drink lots of water and try to figure out which of my two hypothesis is correct (if any) and fix it.

If you don't get any better in two or three days or start getting worse go to a doctor; chest pains are something you don't want to play around with.

you could did you get hit by something, you could have ruptured something, or you could have heart problems that are causing this, or your esophagus could be cut or burned if you have gastric reflex (heart burn) i suggest you either go to a doctor or take a weeks rest

Had that during Lacrosse a couple of times. Just take it easy on the running for a few days, maybe a light jog. Are you drinking enough water, that may be the problem.

That sounds like your insidey parts are in poor shape.

you, doctor, now

Get yourself checked by a doctor, chest pains + taste of blood doesn't sound too good. have you actually coughed up or spat out blood?

No that's the thing i can only taste it but i have been coughing up a lot of flem so i don't know if i could have some kind of chest infection
