Explanation
Issues with organs, such as your spleen, stomach, kidney and part of your colon and blood vessels in your abdomen can cause left upper abdominal swelling.

- Pain: If the swelling comes with pain, especially sharp or severe pain, it could mean something serious.
- Fever: A fever might mean there is inflammation or an infection.
