I am not sure I've ever had the flu before. I know the general symptoms (fever, cough, sore throat, etc.), but do the symptoms all come at once on the same day? Or do some symptoms appear first, and later others?
And do all the symptoms disappear together? Or one-by-one?
Can you have a symptom, and then not, and then have it again? Like, can you get a fever for a day, then off a day, then back on a day?
Plus, does fever with the flu rise and fall during the day? Or is it always hot?
Can the fever be low-grade or must it be high?
