My 21 yr old son has been sick for about 2 wks with an extremely sore, swollen throat , enlarged tonsils with white spots, and extreme fatigue . He has tested negative for strep , negative for mono, and his CBC is within normals ranges. He goes back to college next week, but he is still so ill I don t know how he will do that. He sleeps so much and his throat looks horrible. What would you suggest?
