When having the flu do you experience all symptoms at the same time or no?

Influenza symptoms: As with any medical condition, whether infectious or not, patients don't always have to experience every textbook symptom all the time in the order listed. This can make it tricky for your doc to make diagnosis especially if you only have 1 or 2 symptoms of an uncommon condition. So if you don't feel healthy, talk to your doc & keep him/her updated as to your symptoms. Same for drug side effects.
