I think I might have heart attack!?

Call 911!!! If you feel pressure-type chest pain, going to your shoulder or jaw, and have associated shortness of breath, these are classic signs. Remember, only about 1/3 of heart attacks present with these classic signs. Some show up as nausea, vague discomfort, or no signs at all. If you have any question, err on the side of caution and get to the er immediately. Chew an adult Aspirin while waiting.
Agree w Dr. Hetzler. Heart attack symptoms can include: chest pressure, pain or tightness that can radiate to arms, neck, jaw or back; nausea, shortness of breath, sweating, lightheadedness, dizziness, fatigue, anxiety or a sense of impending doom. Some heart attacks are silent. Get evaluation urgently.
