Why am I having lower pains in my stomach?

Many causes. Lots of things can cause the stomach to hurt down low. The organs in the lower abdomen include the large intestines, bladder, and ovaries/uterus. Hernias can also cause pain in this area. See your doctor, and be prepared to answer the questions: is it associated with eating? What makes it worse/better? Do you have any diarrhea, constipation, nausea? Is it associated with your period? With sex?
