The pain is not only sudden but severe, and unlike any stomachache you've ever had. You may have an intestinal obstruction, appendicitis, or acute pancreatitis and require immediate medical attention.
The pain is high in the middle of your abdomen and goes into the center of your chest, neck, or shoulders. You could be having a heart attack. Call 911. Chew and swallow an aspirin, and drink a glass of water—this thins the blood, helping to get more of it to the heart.
