Abdominal pain. Abdominal pain, also known as stomach pain or tummy ache, is a common symptom associated with non-serious and serious causes. Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. In a third of cases the exact cause is unclear.
Acute abdominal pain develops, and often resolves, over a few hours to a few days. Chronic abdominal pain may be intermittent, or episodic, meaning it may come and go. This type of pain may be present for weeks to months, or even years. Some conditions cause progressive pain, which steadily gets worse over time.
