Although you had Mono a several weeks in July, there are some symptoms of Infectious Mononeucleosis (IM) that appears to linger on. Spleen enlargement or splenomegaly for instance.
The spleen is an organ that is a part of the lymph system that filters blood and maintains healthy red and white blood cells and platelets. Appropriate limitation of activity, including avoiding contact sports, will help prevent trauma that might cause the spleen to rupture.
Severe abdominal pain is usually rare in IM, except with spleenic rupture. This is an serious compication which may requires massive transfusions and immedicate splenectomy.
Therefore, I would acvice you to consult with your Healthcare provider regarding this issue. He/She will perform a thorough exam of your abdomen to check for an enlarged spleen.
Not having insurace is no excuse for not trying to get insurance. In fact, I would recommend that you get insurance before you are diagnosed by a Physician when most insurance carries will not allow you coverage.
Hope this answers your question!
