Your left ribs protect the organs that sit below them, like your heart and your stomach. 

Pain in this area can be caused by injury, infection, or an underlying condition.

If you have pain in your chest, you might worry about a serious condition, such as a heart attack. While it’s true that pain under your left ribs can be a heart attack symptom, discomfort in that area is not always related to your heart.

Depending on the cause, left rib pain might feel sharp and stabbing, or dull and aching. For many people, pain in this area is due to a benign (not harmful), treatable cause. But if you’re having chest pain, it’s best to see a doctor or healthcare professional to make sure it’s nothing serious.
