My daughter was very very sick with mono. She had swollen eyes, sore throat, tender stomach, VERY BAD HEADACHE, enlarged spleen, vomiting... I was a wreck because at first they didn't know what was wrong with her. He boyfriend at the time never got Mono and that was very weird cause he should had gotten it.
Don't mess around it you have it. Make sure they check your spleen. If it is enlarged you can't do sports for a few months. It can rupture.
