Depending on gender, there are several disorders and conditions of the reproductive system that can cause left flank pain.

In women, the most common reasons for chronic left flank pain are related to ovulation. Mid-cycle pain, also called Mittleschmerz, refers to the pain during ovulation when then the eggs are released from the ovary. Polycystic ovarian syndrome, a common disorder in women, can cause pain in the lower abdomen on the left side and tends to be reoccurring. If a cyst on the ovaries becomes twisted or ruptured, it can be very painful on both sides of the abdomen. Ectopic pregnancy, a miscarriage, pelvic inflammatory disease, and endometritis can all also cause left flank pain.

Surprisingly, appendicitis can cause left flank pain. Although the normal symptom of appendicitis is right flank pain, in rare cases left flank pain results instead. The large intestines can become infected or twisted, causing pain on the left side. An enlarged or infected spleen can also be to blame for left flank pain.
