5 Abdominal Pain Warning Signs
Lower Abdomen Pain

Pain in the lower abdomen is located above the pelvic bone or near the lower region of the intestines. Lower abdomen pain may be associated with menstrual cramps, an intestinal obstruction, appendicitis, or problems with pregnancy. See a doctor immediately if rectal bleeding occurs in addition to abdominal pain as this may be an indication of a serious disease.
Upper Abdomen Pain

Upper abdominal pain may be an indication of liver problems such as hepatitis (inflammation of the liver). Pain in the upper abdomen may also be associated with gallstones, pneumonia, or a heart attack. The combination of upper abdominal pain and nausea may be a sign of heartburn or acid reflux. Pain located in the upper abdominal area may also indicate an enlarged spleen, hard stool that cannot be passed, or an injury.
