Dull radiation pain in pelvis with loose motions. what does this mean for women?

Gastroenteritis: It sounds like you have gastroenteritis with crampy abdominal pain/pelvic pain and diarrhea. I would wonder if you ate anything unusual, traveled somewhere, or were around anyone that was sick with a similar diarrheal illness. If it doesn't go away shortly, or if symptoms worsen, you need to call a doctor for help. They can make a diagnosis and help plan out your treatment.
