What could cause pain on the lower left side of my stomach?

There are several reasons why you might feel pain in your lower left abdomen. One common cause is diverticulitis, which happens when small pouches in the colon become inflamed. Sometimes, if the colon or bowel is upset from constipation or an infection, it may hurt too. Though the appendix is usually on the right side, there are rare cases where an inflamed appendix shows up on the left side, known as left-sided appendicitis.

Other possible causes include kidney stones or issues related to the reproductive organs in women. In one report, doctors found that a type of blood cancer called multiple myeloma could even start with pain in this area, though this is very uncommon. When figuring out the reason for your pain, doctors may use imaging tests like CT scans and blood tests to get a clearer picture of what is happening inside.
