Symptoms of diverticulitis may last from a few hours to several days. These symptoms may include:
- Tenderness, cramps, or pain in the abdomen (usually in the lower left side but may occur on the right) that is sometimes worse when you move.
- Fever and chills.
- A bloated feeling, abdominal swelling, or gas.
- Diarrhea or constipation.
- Nausea and sometimes vomiting.
- Loss of appetite.
Complications also can cause symptoms. If an abnormal opening (fistula) develops between the colon and the vagina or the colon and the urethra, you may pass air or stool from the vagina or the urethra.
