10. You Feel a Sudden or Severe Pain in the Abdomen

There are times when a twinge in the stomach is normal, like after a heavy meal or during their period for women, and then times when it’s not. A sudden, sharp stomach pain, especially under your diaphragm, falls squarely into the latter of those categories.

This is because the pain could have been caused due to a ound or perforation of the gastrointestinal lining in your stomach or intestine, or an inflammation in the intestinal tract. Or you could have appendicitis, or a build up of gallstones. Other chronic illnesses like colitis or irritable bowel syndrome also cause severe abdominal pain.
