Why am i getting these heart/chest pains when i exercise in some form, feels like a headache in my heart and it gets me to the point i want to cry?

Get checked out: It's always important to check out causes for chest pain, especially if it happens when you exercise. At your age, actual heart disease is unlikely but certainly not impossible. Get to the bottom of it so you can stop worrying about it and exercise without pain or fear.

Need cardiav evaluat: You did not mention your age, but chest pain on left side of chest may be due to angina and you need cardiac evaluation, ekg, blood test to check your cholesteroland sugar etc, nuclear stress test and if positive coronary angiogram.So have it checked out we also want to know if you have other risk factors like smoking, obesity, diabetes, hypertension, high cholesterol and family history of heart disese.

Depends on age: If you are an adolescent or young adult with a healthy past history, these are probably benign symptoms. If you are older or sickly, they be more significant. See your doctor to elucidate the causes of your concerns.
