    • Ectopic Pregnancy: A pregnancy outside the uterus can be life-threatening and requires immediate attention.
  4. Spleen Issues
    • An enlarged spleen (splenomegaly) due to infection or other conditions may cause pain or fullness under the left rib cage.
  5. Muscle Strain
    • Overexertion, heavy lifting, or injury to abdominal muscles can lead to localised pain on the left side.
