Chest pain may result from diminished capacity of the heart, blocked arteries, pneumonia, severe asthma, a broken rib or cartilage, gastroesophageal reflux disease (GERD), heartburn or even a hiatal hernia. You may not be able to discern if it is coming from the heart without proper testing.
It is very important to determine the cause of any chest pain. During a heart attack, men and women can show very different symptoms. Sometimes, pain is directly in the chest like a crushing feeling; sometimes it radiates up the neck and into the jaw or down an arm; it can feel fleeting; it can cause numbness, confusion, profuse sweating with weakness (diaphoretic); sometimes the pain is more in the back than the front; sometimes there is shortness of breath and weakness; there can be sudden loss of consciousness; elevated heart rate (tachycardia) or a very slow heart rate (bradycardia).
Only a medical professional can properly determine and treat the cause of your chest pain.
