Possible causes of pain in the lower and upper left-side of the abdomen include kidney infection, cancer and diverticulitis, states Mayo Clinic. Many other conditions are specific to whether the pain is located in the upper or lower left-side of the abdomen.

For instance, pain that occurs in the upper left-side of the abdomen can indicate a heart attack, enlarged spleen, hiatal hernia or shingles, explains Mayo Clinic. Pain that occurs in the lower left-side of the abdomen can include an inguinal hernia, thoracic aortic aneurysm or intestinal obstruction. Additionally, many conditions can cause abdominal pain that is very general in some people, and localized pain in others. Some conditions that may cause generalized pain include urinary tract infection, thoracic aortic aneurysm, appendicitis and intestinal obstruction.

Call 911 for abdominal pain that is a result of trauma, such as a car accident, or is accompanied by pain or pressure in the chest, states Mayo Clinic. Seek prompt medical attention for abdominal pain that is severe in nature or accompanied by swelling of the abdomen, stools that contain blood, or nausea and vomiting that do not improve. Also seek immediate medical attention for an abdomen that is tender to the touch or if a person has skin that appears yellow, accompanied by pain.
