When you breath through your nose the air becomes warm and moisturized. through your mouth it doesnt. so the air stays cold and dry, which irritates your airways.

No
This is just a regular cramp from running, run more, build up your endurance and all should be alright.
It does not hurt because you are not running hard enough. You have to exert yourself.
no
my lungs are score from coughing so much
You are exhausted and your are irritating your lungs by the rapid and heavy breathing. I ran a few miles in the cold once and my lungs burned, that could also be the reason. I could not stop coughing for at least an hour.
