I suggest you rad up about mono on the net

I'm pretty sure it could. I had mono in the fourth grade (now I'm a sophmore and its too diffulcult to be in sports) and have all but the stomache pain. I've had exrays to see what has been causing chest pain, plenty of heart tests, like echocardiograms and crap. But a girl my mom works with just asked if i have had mono, which brightened my day I'm possibly diagnosed, and said i could have a possibly post virus from mono, ask your Dr. about it and see what they say, hope you get well, I know what your going through! God be with you.
