It could be several things. If you are experiencing heart attack (what happens BEFORE cardiac arrest) symptoms (yes, even young women can have them), you would be feeling a heaviness in the center of your chest, like someone is kneeling on it, and pain radiating down your LEFT arm. You would also have profuse sweating, distended neck veins, and be struggling to get a breath.
Other things could be as simple as heart burn/indigestion (does the pain occur after eating?), reflux disease, a pulmonary (lung) issue like emphysema (do you smoke?), or strained chest muscles if you lift heavy things (including your children!) or have started an exercise routine that involves weight/resistance training.
