Alright... So i'm 17, in pretty good health, and 5 weeks into my first semester living on-campus. For about the past 3 weeks or so i've had a moderate sore throat, low-grade off-and-on fever, pain in (what feels like) my ovaries, and (most disconcertingly of all) an arrhythmia and chest pain and a possibly swollen right atrium.

In addition to that, I feel exhausted all the time. I could easily sleep 18 hours a day or more if my schedule would permit me to. My aunt and uncle (and apparently my immediate family now) have mono, and my aunt said some of my symptoms sound like hers. When I went to have the ultrasound done of my heart, my left rib was really sensitive when the tech touched it.

Can mono cause a heart problem, such as an arrhythmia or swelling? The test came out negative, but I know that mono tests aren't always reliable. Should I go home and get the ebv titer drawn?
