What might cause left side pain under the ribs in females?

There are several reasons you might feel pain under your left ribs. One common cause is slipping rib syndrome. This happens when one of your ribs moves or shifts out of place, which can hurt a lot. Another possibility is intercostal neuralgia, where the nerves between your ribs become irritated or stretched, causing sharp or burning pain. Although it is less common, Nutcracker syndrome could also be a reason. This condition involves the squeezing of blood vessels near the kidney and sometimes causes pain that spreads to the rib area or even the lower back. All these conditions affect parts of the body near your ribs in different ways. Because the cause of the pain can be different for each person, it is important to pay attention to what the pain feels like, how long it lasts, and if you have any other symptoms. If this pain bothers you or gets worse, you can start by using a free symptom checker to help identify possible causes, though it's always a good idea to speak with a doctor so they can run tests and help you feel better.
