Parents are urged to contact a physician immediately if their child’s stomach ache is severe and lasts more than one hour, or is accompanied by any of the following:

• Pain in the lower right side accompanied by fever, which may indicate appendicitis
  
  
• Blood in the stool or urine
  
  
• Recent history of surgery or abdominal injury
  
  
• Reason to suspect that the child has been poisoned

Symptoms accompanying stomach aches that require less urgent medical attention include low-grade fever, sore throat or diarrhea that occurs more than twice during the course of the stomach problem. In addition, stomach pain that gets steadily worse over several hours also requires medical attention.
