10 Causes of Spleen Pain
Cause #4: Viral Infections
Some viral infections such as mononucleosis can cause splenic complications. Mononucleosis is an infectious disease that is also called mono or glandular fever. Its other name, kissing disease, is used because the disease is easily transmitted through kissing or exchange of oral fluids. Mono infections are usually self-limited. However, they can lead to serious complications.
In some cases, mononucleosis can cause splenic pain due to the enlargement of the spleen (splenomegaly). In extreme cases this can lead to splenic rupture, causing a sharp, sudden, and intense pain in the upper-left part of the abdomen. Although rare, splenic rupture is the leading cause of death in patients with this disease. Patients with mononucleosis who present with splenomegaly should avoid physical activity, and take precautions to avoid trauma to the chest or abdomen.
