Hi, I am college student and think I have the flu. The first day I woke up with chills, then sweating, which I think was my fever breaking? I also had lots of pain in my eyes, coughing, diarrhea, and a headache. I have stayed home in bed for the last two days and feel much better today. Online it says that it takes two weeks for the flu to heal. Is it possible I could be better in less than a week? Or do I have something else?
