The last portion of your colon calls the left side of your lower abdomen home. In the case of some women, it is also home to the left ovary. When the pain is the area is minor, you most likely have nothing to worry about. It will most likely clear up within the next one or two days even if it doesn’t receive medical attention.
That said, if the pain you’re experiencing in that area is caused by an injury or accident, it’s imperative that you call your local emergency service immediately to avoid any serious complication. You should also call 911 if the pain in your lower left abdomen is accompanied by pain or pressure in the chest area.
