Throbbing pain in the lower left abdomen can be caused by appendicitis, kidney stones, ovarian cysts, Crohn's disease and cancer, according to Mayo Clinic. Other possible causes are a hernia, intestinal obstruction or torn colon.
Appendicitis is a common source of abdominal pain that starts in the middle of the stomach and moves to the lower left abdomen, says Mayo Clinic. If the appendix is not removed, the pain gets worse and could be life-threatening. Kidney problems such as kidney stones or a kidney infection can also cause lower left abdominal pain. A person with a kidney infection also experiences burning and persistent urination, fever and blood in urine along with flank, back and abdominal pain. Kidney infections need to be treated immediately to prevent permanent kidney damage and blood poisoning.
Women with ovary issues such as ovarian cysts, endometriosis and Mittelschmerz experience lower left pain, explains Mayo Clinic. Endometriosis causes pain because the lining in the uterus grows out of control outside of the uterus. This can cause cysts to form on the ovaries. Infertility and ovarian cancer can develop. Mittelschmerz usually causes pain halfway between two menstrual periods, although the pain is not intense and does not have any serious complications.
