Can appendicitis cause bowel spasms?

POSSIBLY. Appendicitis usually presents as a vague pain around the navel and mid-abdomen, which then progresses to right lower quadrant over 12 to 24 hours. Some patients might perceive the pain as a cramp, or spasm. Diarhea is usually not associated, but loss of appetite is. Certainly, as the disease progresses, fever can develop. Good luck.
