My daughter turned 14 two months ago. She had mono the first time at 8 years old, the second time last February at 13 years old, and now going through her third bout with it at 14 years old (and less than 8 months since she last had it). Her pediatricians keep saying it is being caused by three different viruses, advising her to stop sharing water bottles, etc. WHO GETS MONO THREE TIMES IN THEIR LIFE? Clearly there is something else going on. Did any of you experience multiple mononucleosis episodes? If so, please tell me where to go from here - rheumatologist, geneticist, immunologists? Never been at this level of worry in my life and never felt more confused as to where to turn for understanding, answers, and most importantly, treatment.
