So, on Thursday I came down with the flu, Had a fever of 101.3, progressed throughout the weekend and on Sunday I still had a fever of 100.6.I woke up with no fever, so I went to school today(Monday) and went to football conditioning where we had one of the most intense cardio and body bulking workouts. I tried my best to keep up but the coughing and nausea set in, and now I m experiencing the symptoms of the flu again. Is it possible the flu came back because I wasn t fully recovered, or is it just that I m worn out?
