Both my daughters had similar symptoms but moreso for my younger one age 45. the rib pain, under armpit pain and bumps. Both were diagnosed with Epstein-Barr virus (EBV) and mononucleosis
SEE YOUR DOCTOR HE can test for antibodies to the following EBV-associated antigens:
• Viral capsid antigen (VCA)
• Anti-VCA IgM
• Early antigen (EA)
Anti-EA IgG
• EBV nuclear antigen (EBNA)
One daughter had a swollen spleen and liver
hope this info helps
