Symptoms

The signs and symptoms of diverticulitis include:

• Pain, which may be constant and persist for several days. The lower left side of the abdomen is the usual site of the pain. Sometimes, however, the right side of the abdomen is more painful, especially in people of Asian descent.
• Nausea and vomiting.
• Fever.
• Abdominal tenderness.
• Constipation or, less commonly, diarrhea.

When to see a doctor

Get medical attention anytime you have constant, unexplained abdominal pain, particularly if you also have a fever and constipation or diarrhea.
