When Should I Worry about Upper Left Abdominal Pain?

Pain in the upper left abdomen typically stems from the stomach but may also be related to the spleen, colon, pancreas, or muscles. While the pain in this area is often mild and not serious, you should be concerned if it becomes severe, constant, or worsens over time. Pay close attention if you develop additional symptoms like high fever, vomiting, dizziness, rapid heartbeat, or breathing difficulties. These warning signs could indicate an infection or organ injury—particularly to the spleen. If you've recently experienced trauma to your side and develop this pain, it may signal internal bleeding. Additionally, seek immediate medical attention if the pain interferes with daily activities or causes severe weakness. For your safety, have a doctor evaluate these symptoms, conduct necessary tests, and determine appropriate treatment.
